Patent ID: 7883282

Claim:
An image forming apparatus comprising: an image forming device configured to form an image on a recording sheet; a sheet feed tray that is configured to be loaded with the recording sheet; a sheet feed roller configured to convey the recording sheet toward the image forming device by rotating while contacting the recording sheet; a conveyor roller disposed downstream of the sheet feed roller in a recording sheet conveying direction, the conveyor roller configured to apply a conveying force on the recording sheet by rotating while contacting the recording sheet; a sheet position detection device configured to detect a position of the recording sheet, fed from the sheet feed tray, in a recording sheet conveying path (L) extending between the sheet feed tray and the image forming device, wherein the conveying path is defined by an outer guide member and an inner guide member of the apparatus; and a conveyor roller control device configured to control a rotation amount of the conveyor roller over a reference time period in accordance with the position of the recording sheet detected by the sheet position detection device, the conveyor roller control device increasing the rotation amount of the conveyor roller to a first rotation amount, wherein the first rotation amount of the conveyor roller over the reference time period is greater, when the recording sheet being conveyed is in contact with the sheet feed roller and the conveyor roller, than a second rotation amount of the conveyor roller over the reference time period corresponding to when the recording sheet being conveyed is not in contact with the sheet feed roller while being in contact with the conveyor roller, wherein the conveyor roller control device is further configured to increase the rotation amount of the conveyor roller to a third rotation amount over the reference time period upon determining that the recording sheet has transitioned from a first state in which the recording sheet is in contact with the outer guide member to a second state in which the recording sheet is in contact with the inner guide member, wherein the third rotation amount is greater than the first rotation amount.
