    • An image forming apparatus includes a sheet feeding cassette, transport rollers, a pick-up roller, a sheet detector, and a control section. The sheet feeding cassette stores sheets for developer images to be transferred thereonto at a secondary transfer position. The transport rollers transport a sheet at variable speeds along a sheet transport path which extends from the cassette to the secondary transfer position. The pick-up roller feeds a sheet into the sheet transport path. The sheet detector detects whether a sheet is fed from the cassette. When the detector detects that a sheet is not fed, the control section controls the pick-up roller to feed the sheet again. The control section varies respective transport speeds of the pick-up roller, a sheet feed roller, and the transport rollers, according to number of attempts to feed the sheet.
