Abstract:
1. An image forming apparatus comprising: an image forming unit adapted to transfer an image formed on an image carrier onto a sheet; a fixing unit adapted to fix a transferred image on the sheet; a sheet shifting unit located upstream of said image forming unit in a sheet conveying direction and adapted to shift a position of the sheet in a lateral direction, orthogonal to a sheet conveying direction, to one of a plurality of target shift positions so as to change a position where an edge of the sheet passes through said fixing unit from that of another sheet on which a transferred image is to be fixed by said fixing unit; a shift position determining unit adapted to determine the one of the target shift positions where the sheet is to be shifted by said sheet shifting unit; and an image position determining unit adapted to determine a position of the image to be formed on the image carrier in the lateral direction on the image carrier on the basis of the target shift position determined by said shift position determining unit and a tolerance preliminarily set with respect to each of the target shift positions.
