An image forming apparatus includes an image carrier that is rotatable; a transfer member that is rotatably disposed so as to face the image carrier, the transfer member transferring an image carried by the image carrier to a sheet; a leading end gripping member that is attached to the transfer member, the leading end gripping member gripping a leading end of the sheet in the transport direction on an outer peripheral surface of the transfer member; a trailing end holding member that holds a trailing end of the sheet in the transport direction between the trailing end holding member and the outer peripheral surface of the transfer member; and a controller that changes a distance between the leading end gripping member and the trailing end holding member when holding the sheet on the basis of a length of the sheet in the transport direction.
