摘要： Disclosed are a developing device, a developing cartridge, a process cartridge, and an image forming apparatus in which image deficiency is prevented by absorbing the tolerance of each component and making the position of the developing roller in the thrust direction constant and which are easy to assemble. A frame member is equipped with an urging unit that axially urges the developing roller, the urging unit urging the developing roller in the direction of movement of the developing roller by the thrust force of a helical gear when a driving force is transmitted to the developing roller, to thereby make the position of the developing roller in the thrust direction constant.
