PROBLEM TO BE SOLVED: To improve image quality by preventing phase shift in the meshing of a driven gear in a developing cartridge with a driving gear in an image forming device main body from being caused on both sides at the time of attaching the developing cartridge in a developing device in the image forming device. SOLUTION: The driven gears 61 are fixed at both ends of the center shaft 60 of a developer carrier provided in the developing cartridge, and respective cap members 63 are attached to the outside of the gears 61. At the time of attaching the developing cartridge in a printer device main body (image forming device main body), both cap members are put in the linear grooves 68 of guide members 67 on both sides, and made to abut on the engaging part 71 of a leaf spring member 70 so as to temporarily increase the insertion resistance of the developing cartridge, whereby the inclination of the developing cartridge is corrected. Thus, the gear 61 is meshed with the driving gear 72 without causing the phase shift. |
