Abstract
To reduce attachment and detachment resistance in attaching and detaching a cartridge.SOLUTION: An image forming apparatus 1 comprises: a main body housing 10; a cartridge (drum cartridge 20); an electric contact CR; and a guide groove G. The cartridge has a memory (toner memory 36), a memory holder 70, and a memory holder cover 80. The memory has an electric contact surface 36A. The memory holder cover 80 holds the memory holder 70 movably in the vertical direction. In a state in which the cartridge is at a mounted position where it is mounted in the main body housing, the electric contact CR is brought into contact with the electric contact surface 36A from above. The guide groove G is located in a side wall on one side in an axial direction of the main body housing 10. The guide groove G has an upper guide surface 100 and a lower guide surface 200. In the state in which the cartridge is at the mounted position, the electric contact surface 36A is parallel to at least part of the upper guide surface 100 and the lower guide surface 200.SELECTED DRAWING: Figure 13
