Patent ID: 8548360

Claim:
A toner cartridge converting device, comprising: a photoreceptor drum, wherein an electrostatic latent image is formed on the circum surface of the photoreceptor drum; a toner supply unit, providing toners on the electrostatic latent image in association with the rotation of the photoreceptor drum and having a plurality of toner cartridges adjacent to the circum surface of the photoreceptor drum; and a driving module, disposed at a side of the photoreceptor drum which is the same as that of the toner supply unit and sequentially making the toner cartridges relatively move along a radial direction of the photoreceptor drum in association with the rotation of the photoreceptor drum, wherein the driving module comprises a rectangular bar serving as an operation part for leaning against the toner cartridges and the moving direction of the rectangular bar is perpendicular to the moving direction of the toner cartridges, the operation part has a positioning groove formed on an side surface relatively far away from the photoreceptor drum so that a toner cartridge located in the positioning groove is more adjacent to the circum surface of the photoreceptor drum than other toner cartridges.
