IMAGE READING DEVICE, IMAGE FORMING APPARATUS, AND IMAGE READING METHOD
An image reading device includes: a conveying portion configured to convey a sheet; a reading portion configured to read an image of the sheet; a driving portion configured to drive the conveying portion; and a switch processing portion configured to switch an operation mode of the driving portion alternately between a drive mode for driving the conveying portion and a cool mode for cooling the driving portion. When, in the drive mode, a total driving time of the driving portion exceeds a first threshold, the switch processing portion switches the operation mode to the cool mode.
An image reading device includes: a first reading portion configured to read an image of a sheet; a second reading portion disposed below a contact glass; a first white reference plate disposed in a conveying portion to face the first reading portion; a second white reference plate disposed in the conveying portion at a reference position that can face the second reading portion; and a control portion configured to light a first light source and generate first white reference data by using reflected light reflected from the first white reference plate, and light a second light source and generate second white reference data by using reflected light reflected from the second white reference plate. The control portion controls the first light source and the second light source such that a lighting time of the first light source does not overlap with a lighting time of the second light source.
A sheet conveying device includes a first roller, a second roller, and a pressing portion. The pressing portion includes a pressing member contacting the first roller from its side opposite from the second roller and a pressing urging member urging the pressing member toward the second roller. The first roller has a step portion formed in an outer circumferential part of it all over its circumference. The step portion has an outer diameter smaller than the outer diameter of a contact region with the second roller and is contacted by the pressing member.
An image forming apparatus includes a developing device, a container, a toner replenishment device, a toner conveyance detection portion, and a control portion. The toner replenishment device includes a plurality of toner replenishment paths through which toner in the container is conveyed and replenished to the developing device. The toner conveyance detection portion detects a toner conveyance error in toner conveyance performed by using the plurality of toner replenishment paths. In a case where the toner conveyance detection portion has detected a toner conveyance error in one of the toner replenishment paths that is in use, the control portion switches to another one of the toner replenishment paths to convey the toner.
A developing device includes a developer container, a conveying member, and a developer carrying member. The conveying member has a rotation shaft, a conveying blade, a cut portion, and a dispersing portion. In the cut portion, the conveying blade is partly cut off along the longitudinal direction of the developer container.
