ABSTRACT:
An elastic member for urging a developer carrier in the direction of an image carrier is located in a casing of a developer cartridge. Since the elastic member will be new whenever the developer cartridge is replaced, an urging force of the elastic member will not deteriorate over time. Thus, a proper pressing state of the developer carrier on the image carrier is maintained. Thus, the amount of toner supplied from the developer carrier to the image carrier is stable. Thereby, a picture of high quality can be formed continuously without poor development by poor pressure between the developer carrier and the image carrier.
