Abstract
An image forming apparatus includes a print head, an endless belt, a pressure roller, and a controller. The print head is configured to eject droplets of ink from multiple nozzles onto a recording sheet. The endless belt is stretched around at least first and second rollers, and is configured to convey the recording sheet placed on an outer surface thereof. The pressure roller is configured to exert pressure against the outer surface of the endless belt. The controller is configured to move the endless belt into a correcting position where the pressure roller meets a given portion of the endless belt. The given portion of the endless belt is previously retained in contact with the first roller and develops deformation due to the previous retention. The pressure exerted by the pressure roller corrects the deformation while the endless belt is in the correcting position.
