Abstract
In an image forming apparatus, a development cartridge is movable between a contact position in which a development roller is in contact with a photosensitive drum and a separate position in which the development roller is separate from the photosensitive drum, by a cam and a cam follower that is caused to slide in directions parallel to a rotation axis of the cam between a push position in which the development cartridge is pushed by the cam and positioned in the separate position and a no-push position in which the development cartridge is in the contact position. The cam follower includes a first shaft and a contact arm extending from the first shaft and configured to contact a cam surface of the cam. A projection of the first shaft onto the first cam in a direction parallel to the rotation axis is positioned inside a contour of the first cam.
