Claim:
An image forming apparatus comprising: an image carrier; an image forming section to form an image on the image carrier; a transfer section to transfer the image carried by the image carrier onto a recording sheet; a sheet conveying section which conveys the recording sheet fed from a sheet feeding section toward a transfer position with controlled timing, the sheet conveying section comprising: a pair of registration rollers; a pair of loop rollers being disposed upstream of the registration rollers in a sheet feeding direction wherein the pair of loop rollers rotates during a prescribed period to make a front edge of the recording sheet hit a nip portion of the pair of registration rollers being stopped to form a curve of the recording sheet and align the front edge to the nip portion; and a detection section which detects the recording sheet having passed through the sheet conveying section; and a movable conveying unit configured to move, based on a sheet detection signal of the detection section, the pair of registration rollers and the pair of loop rollers as a unified body when correcting at least a lateral misalignment of the recording sheet, which is a misalignment in a vertical direction to the sheet feeding direction, and inclination of the recording sheet, before the transfer section transfers the image onto the recording sheet.
