An image forming apparatus includes an optical detection unit which detects the presence of a copy paper and determines an offset amount of the copy paper in the direction perpendicular to a feeding direction of the copy paper. An adjusting unit adjusts a position of a visible image, in the direction perpendicular to the feeding direction of the copy paper, formed on the copy paper by a visible image forming unit on the basis of the determination of the detection unit. The image forming apparatus may also include a comparing circuit which compares an actual feeding time interval of the copy paper between an aligning roller pair and the detection unit with a prescribed feeding time interval and determines a discrepancy therebetween and a control circuit controlling a commencement timing of the operation of a scan member on the basis of the result of the comparing circuit, thus enabling the image forming apparatus to adjust a position of the visible image, in the feeding direction of the copy paper, formed on the copy paper. |
