することを特徴とする現像装置。 It consists of a cylindrical toner replenishment cartridge having an opening on its circumference and containing replenishment toner therein, and a developing container having a mounting portion into which the toner replenishment cartridge is removably fitted. After fitting the toner replenishment cartridge into the developer container by sliding the provided protrusion along the recess provided in the mounting portion, the toner replenishment cartridge is rotated to supply the replenishment toner into the developer container. In the developing device configured to replenish the toner, the toner supply cartridge has a claw member at the front end in the mounting direction, and is rotated and axially moved by engaging with the claw member at the rear end of the mounting portion. A developing device comprising: a rotating member that moves; and a regulating member that contacts the rotating member and regulates the direction of rotation, thereby limiting the number of times the toner supply cartridge replenishes toner.
