An image forming device has: an image carrying member (21), a developing cartridge (40), a toner cartridge (60), and a transfer unit (23). The image carrying member has a surface on which an electrostatic latent image is provided. The developing cartridge contains a developing roller (41) and a single auger (45). The developing roller has a rotation axis extending in an axial direction and a cylindrical surface on which toner for developing the electrostatic latent image is carried. The auger conveys the toner along the axial direction. The toner cartridge is detachably attached to the developing cartridge and containing the toner. The toner cartridge has an agitation mechanism (84-85) that agitates the toner, a conveyance mechanism (81-83) that conveys the toner to the agitation mechanism, and two ports, the two ports (64a,b) being aligned in the axial direction and communicated with the developing cartridge, respectively. The transfer unit transfers the developed electrostatic latent image on the image carrying member to a recording medium. The toner cartridge and the developing cartridge are arrayed side by side in a horizontal direction. The toner cartridge has a shape having a vertical cross section in which a horizontal length is greater than a vertical length. |
