Claim:
An image forming apparatus, comprising: a print head configured to eject droplets of ink from multiple nozzles onto a recording sheet; an endless belt stretched around at least first and second rollers, and configured to convey the recording sheet placed on an outer surface thereof; a belt driving unit configured to drive the endless belt; a pressure roller configured to exert pressure against the outer surface of the endless belt; and a controller configured to determine that a specific portion of the endless belt has been retained in contact with the first roller and has developed a deformation due to said contact with the first roller, the controller controlling the belt driving unit to move the endless belt into a correcting position and hold the endless belt in the correcting position at which the pressure roller meets said specific portion of the endless belt that has been retained in contact with the first roller wherein the pressure exerted by the pressure roller corrects the deformation while the endless belt is held in the correcting position.
