摘要：
An image forming apparatus has a recording medium bearing member bearing a recording medium thereon and rotatable, the recording medium bearing member having in the surface thereof a recess extending in the direction of the rotary shaft thereof, image formation being effected on the recording medium born on the recording medium bearing member, and a rotatable member abutted against the recording medium bearing member, the rotatable member being provided with a abutting portion abutted against the recording medium bearing member, and a regulating portion adapted to abut against the recording medium bearing member when the recess and the rotatable member become opposed to each other. Thus, the distance between the recess and the bearing portion, is regulated the rotatable member being movable between a first position in which the abutting portion abuts against the recording medium bearing member and a second position in which the regulating portion abuts against the recording medium bearing member. The regulating portion is spaced apart from the recording medium bearing member when the abutting portion is abutted against the recording medium bearing member.
