Abrégé

A two-color pen includes a pen body, a roller and water supply components; the roller is rotatably provided at the head of the pen body; there is at least one pair of water supply components, a reset device for pushing the water supply components to be in contact with the roller is provided in the pen body; and the roller is provided with a transmission part which alternatively pushes two water supply components in pairs in the direction away from the roller in sequence. The reset device in the two-color pen can push the water supply components outputting different colors in the direction of the roller. When the roller is rolling, the transmission part provided on the roller can alternately push the two water supply components in pairs in the direction away from the roller in sequence, so that the water outlet ends of the two water supply components in pairs can alternately abut against the roller in sequence under the action of the reset device. In this way, the roller can draw lines or patterns with two colors, thus better meeting the use requirements of users.
