ABSTRACT:
The present invention provides an image forming apparatus that can perform stable sheet conveyance, regardless of whether a sheet processing apparatus is connected thereto. The image forming apparatus can be connected to a sheet processing apparatus that performs post processing on each conveyed sheet. The image forming apparatus includes: a pair of discharge rollers that are located at the discharge outlet of the image forming main body for sheet conveyance, and have rotational members arranged so as to alternately face both sides of each sheet in the direction perpendicular to the sheet conveying direction; and an upper discharge roller holding member that changes the center distance between the discharge rollers from a first center distance observed when the sheet processing apparatus is not connected to the image forming main body to a second center distance observed when the sheet processing apparatus is connected to the image forming main body to convey a sheet to the sheet processing apparatus.
