PURPOSE:To provide an image forming device equipped with a developing cartridge which accurately positions a member which puts stress on a positional relationship with a developing roller. CONSTITUTION:In addition to a drive gear 10d for driving a toner supply roller 5, first and second idle gears 10b and 10c, respectively, for driving a stirring wing 3 are freely-rotatably supported by the shaft receiving member 7 of the developing roller 4. Thus, because a distance between the shaft and the developing roller is accurately positioned, irregularities in pitch which is caused by uniform gear-pitch is prevented, a satisfactory image is obtained. |
