Abrégé

A distance-measuring apparatus includes a light emitter to emit light with modulated frequency to an object, a light receiver to receive the light that is emitted from the light emitter and returns as reflected by the object, and a controller to measure, based on radiation intensity of received light by the light receiver, a length of time between a time at which the light is emitted by the light emitter and a time at which the light is received by the light receiver to obtain a distance to the object. The controller performs a first measurement in which the light emitter is made emit the light at a first modulation frequency for a first irradiation time and a second time, the second irradiation time being longer than the first irradiation time, to measure the length of time by the time at which the light is received by the light receiver a first plurality of times. The controller performs a second measurement in which the light emitter is made emit the light at a second modulation frequency for a third irradiation time to measure the length of time by the time at which the light is received by the light receiver a second plurality of times fewer than the first plurality of times. The third irradiation time is longer than the first irradiation time and is shorter than the second irradiation time. Both reduction in aliasing and increase in dynamic range can be achieved.

A toner container includes a container body that is used to house a toner and that is detachably attachable to a mounting portion in a developing device; and an operating member that is used to open and close a shutter. The shutter as well as the operating member includes an engaging portion that can engage with a linking member which is disposed in the mounting portion and which can perform a reciprocating linear movement. In the state in which the container body is not mounted in the mounting portion, the shutter and the operating member are in a non-linked state with each other. In contrast, in the state in which the container body is mounted in the mounting portion, the shutter and the operating member become able to be linked to each other via the linking member.

The modification part instructs modification of a portion of a foreground area or a background area which is erroneously divided as a result of dividing predetermined image data into the foreground area being an extraction target and the background area being an out-of-extraction target. The model creation part creates a foreground model of the foreground area and a background model of the background area which are modified, based on first pixel values of a predetermined line segment where the modification is instructed and second pixel values of the foreground area and the background area which are divided. The division part divides the image data into the foreground area and the background area by using the foreground model and the background model which are created by the model creation part.

In an optical sensor, a light emission system emits an irradiated light of a linear polarization in a first polarization direction toward a surface of a target object having a sheet shape from an incident direction which is inclined with respect to a normal direction of the surface. A first light detection system includes a first light detector arranged on a first light path of a specular reflected light, which is emitted from the light emission system and is specularly reflected from the target object. A second light detection system includes a second light detector arranged on a second light path of a diffuse reflected light which is diffusely reflected from an incident plane on the target object. The second light detector receives second light passed by an optical element which passes a linear polarization component of a second polarization direction perpendicular to the first polarization direction.

Abrégé

To provide an image forming apparatus including: a latent electrostatic image bearing member; a charging unit configured to charge the surface of the latent electrostatic image bearing member; an exposing unit configured to expose the charged surface of the latent electrostatic image to form a latent electrostatic image thereon; a developing unit configured to develop the latent electrostatic image with a toner to form a visualized image; a transferring unit configured to transfer the visualized image onto a recording medium; and a fixing unit configured to fix the visualized image transferred onto the recording medium, wherein the toner includes a binder resin and a coloring agent, and the binder resin includes a polyester resin obtained by condensation polymerization of an alcohol component and a carboxylic acid component containing a (meth)acrylic acid modified rosin.

Abrégé

Toner and a developer which are excellent in cleaning property and fixing property at low temperature, and capable of forming images with high quality are provided. A toner prepared by dispersing and/or emulsifying an oil phase or a monomer phase comprising a toner composition and/or a toner composition precursor in a water- based medium to granulate, wherein the toner has an average circularity of 0.925 to 0.970, and the toner composition and/or the toner composition precursor has a layered inorganic material in which at least a part of interlayer ions in the layered inorganic material has been exchanged with organic ions.

Abrégé

An insertion passage 104Y for inserting a suction nozzle 73Y fixed to an image forming apparatus is provided on a holder 102Y, and a connecting passage 114Y that connects the insertion passage 104Y and a toner storage section 106Y of the holder 102Y is provided. After the toner sent from bottle 101Y to the holder 102Y falls towards the connecting passage 104Y, the toner flows into the suction nozzle 73Y through the connecting passage 114Y and is then discharged out of the holder 102Y. An airtightness between the insertion passage 114Y and the suction nozzle 73Y inserted into the insertion passage 114 Y is superior than an airtightness between the bottle 101Y and the holder 102Y engaged with the bottle 101Y.
