Patent ID: 11747764

Abstract:
An image forming apparatus includes a first unit movable to a first inside position of a main assembly and a second unit movable to a second inside position of the main assembly. The first unit includes a first shutter that is rotatable from a first position in which the first shutter opposes a surface of an image bearing member and covers a part of the surface of the image bearing member to a second position in which the first shutter opens the part of the surface of the image bearing member. The second unit includes a second shutter provided with a second contacting portion, with the second shutter being rotatable from a third position in which the second shutter opposes a surface of a developing member and covers a part of the surface of the developing member to a fourth position in which the second shutter opens the part of the surface of the developing member. A moving amount of moving the first shutter from the first position to the second position is less than a moving amount of moving the second shutter from the third position to the fourth position.
