Claim:
An image forming apparatus comprising: an image forming part that forms an image; and a conveyance device that conveys at least one of a recording medium discharged from the image forming part and a recording medium supplied to the image forming device, the image forming part comprising: a rotary member that rotates; a driven member that is driven by the rotary member and conveys a recording medium while holding the recording medium between the driven member and the rotary member; a guide surface, provided on one side of the a rotary shaft of the driven member in a perpendicular direction to a longitudinal direction of the rotary shaft of the driven member, such that the guide surface is in contact with the rotary shaft of the driven member, guides the rotary shaft of the driven member toward the rotary member and is formed so as to be parallel to a virtual surface connecting a rotation center of the driven member with a rotation center of the rotary member; a support member that brings the rotary shaft of the driven member into contact with the guide surface, and along with the guide surface, supports the rotary shaft, wherein the support member is in contact with the rotary shaft of the driven member from a tilted direction with respect to a perpendicular surface of the guide surface, presses the rotary shaft of the driven member against the guide surface, presses the rotary shaft of the driven member toward the rotary member, and regulates a movement of the rotary shaft of the driven member in the opposite direction to the guide surface; a discharge part to which a recording medium is discharged, wherein the driven member is the last member to convey a recording medium to the discharge part; and a space provided in the discharge part which allows free fall of the rear end of a recording medium in a recording medium discharge direction.
