The pressed area 141e mounted on the developer cartridge case 141 is pressed towards a developer cartridge pressing direction X. The developer roller 144 and the photosensitive drum 152 are in contact at a contact position CP. Power is supplied to the developer cartridge 140 when the power supply protrusion 147b connected electrically to the developer roller rotation drive axis 144a and the power supply part 118 mounted on the outside of the developer cartridge 140 are pushed together in the power supply pressing direction S. Here, the power supply pressing direction S is semi-orthogonal to the pressing action line Y that connects the pressing position PP and the contact position CP. Furthermore, the power supply protrusion 147b crosses the pressing action line Y. |
