Abstract
Provided is an image forming apparatus which uses a separation claw to separate a recording medium from a photosensitive member without damaging the recording medium even when the recording medium is thin. The employed separation claw fixed to a frame is a flattened plate made of a resin. The separation claw is gradually tapered toward a leading end thereof, and is provided with a slit from the apex toward the frame . The separation claw is not gradually tapered in a thickness direction and has a constant thickness. A plurality of separation claws are fixed to the frame in a length direction of the photosensitive drum so that the recording medium can be separated regardless of the sheet size. The frame is moved to easily adjust the positional relationship between the photosensitive drum and the separation claws.
