Abstract
An image forming apparatus includes a sheet feed tray for loading a recording sheet, a sheet feed roller that conveys the recording sheet toward an image forming device, a conveyor roller that is disposed downstream of the sheet feed roller in a recording sheet conveying direction and that applies a conveying force on the recording sheet, a sheet position detection device that detects a position of the recording sheet in a conveying path, and a conveyor roller control device that controls a rotation amount of the conveyor roller in accordance with the detected position of the recording sheet. The control device allows the rotation amount of the conveyor roller to become greater, when a recording sheet contacts the sheet feed roller and the conveyor roller, than a rotation amount of the conveyor roller when the recording sheet contacts the conveyor roller but might not contact the sheet feed roller.
