Abstract: Magnification correction of an image is performed by changing the cycle time of an optional pixel in the unit of pixel, until a phase adjustment amount (phase shift value) calculated by fixing the frequency exceeds a preset specified value, and after the phase adjustment amount exceeds the preset specified value, magnification correction of the image is performed by changing the frequency of an image signal in the unit of a line or in the unit of a plurality of lines. Accordingly, the number of execution of the magnification correction of an image by the latter method, in which it is necessary to suspend the image forming operation at the time of execution thereof, can be reduced.

Abstract: A light-emission control unit controls an emission of a light beam from a light-beam generating unit based on an input image signal. A light-beam scanning unit deflects the light beam in a main scanning direction and irradiates the deflected light beam on an image carrier. An anomalous-light emission detecting unit detects an anomalous light emission of the light-beam generating unit when there is no image signal input to the light-emission control unit. A control unit performs an error processing based on the detected anomalous light emission.

Abstract: A test pattern for position adjustment is written on an intermediate transfer body in a sheet interval when a plurality of normal images are written continuously, using a start signal as a trigger. The test pattern is read and fed back by a sensor to adjust image formation control conditions. A normal image on the intermediate transfer body is transferred onto a paper medium supplied in a secondary transfer unit. However, the test pattern passes through the secondary transfer unit without the paper medium being supplied, thereby staining a transfer roller. Therefore, the secondary transfer unit and a transfer belt are separated from each other by a contacting/separating mechanism, while the test pattern written in the sheet interval passes through the secondary transfer unit.

Abstract: A measuring unit measures a time difference between detections of the optical beams by an optical beam detector arranged on either side of an image carrier with respect to a horizontal scanning direction. A magnification correcting unit determines whether a beam spot position adjustment amount corresponding to each of a plurality of developing colors preset by the sub position correcting unit exceeds a threshold preset for each of the plurality of developing colors, and depending on the result of the determination, performs magnification correction of the image by changing a beam spot position interval on a scanning line in units of a line or lines, or by changing a beam spot position interval on a scanning line in units of pixel.
