Abstract:
1. An image forming apparatus comprising: a tray configured to accommodate a plurality of sheets; a sheet conveying path through which the plurality of sheets are conveyed; a sheet feeding unit comprising a sheet feed roller configured to feed the plurality of sheets one by one from the tray through the sheet conveying path to a sheet holding position, and a sheet feed motor configured to rotate to transfer a drive force to the sheet feed roller; a sheet conveying unit comprising: a recording unit configured to form an image onto a surface of the first sheet stopped at the recording position; and a controller configured to control the sheet feed motor and the conveyor motor such that the conveyor roller does not rotate while the recording unit forms an image onto the first sheet, such that the sheet feed roller continues to rotate to feed a second sheet from the tray through the sheet conveying path to a predetermined position which is positioned upstream of the sheet holding position both when the conveyor roller is rotating to transport the first sheet and when the conveyor roller is not rotating while the recording unit forms an image onto the first sheet, and when the second sheet reaches the predetermined position, the sheet feed roller stops rotating, and such that when the conveyor roller stops rotating while the recording unit forms an image onto the first sheet, the sheet feed roller restarts rotating and keeps rotating to maintain colliding of a leading edge of the second sheet against the conveyor roller, which is not rotating at the sheet holding position, to correct a skew of the second sheet.
