PURPOSE: To obtain a process cartridge capable of easily replenishing developer without necessitating a large space and without scattering the developer by storing plural developer replenishing containers from the side face of a developing container. CONSTITUTION: Plural opening parts 4e for inserting the developer replenishing container 8 are provided on one side face of a toner container 4a as the developing container. A guide part 4f is formed from the opening part 4e toward the opposite side face. After the toner runs out in the toner container 4a, the developer replenishing container 8 is inserted in a direction parallel to the axial direction of the photoreceptor drum 1 from the opening part 4e. A projecting part 8c formed on the container 8 is guided along the guide part 4f. After the container 8 is inserted, a toner seal 10 attached to the bottom face of the container 8 is pulled out by picking a knob part 10a up, then, the toner is supplied to the toner container 4a. |
