摘要： This invention makes it possible to prevent any uneven density and degradation in resolution in reciprocal laser scanning using a movable mirror. An image forming apparatus forms an image on a photosensitive member by scanning the photosensitive member with a laser beam reflected by a movable mirror with reciprocating the movable mirror whose rotation angle is changeable in accordance with an electrical signal. The apparatus detects the rotation direction of the movable mirror, and weights, on the basis of the rotation direction, image data of two lines along the sub-scanning direction in correspondence with the ratio of the scanning length after the start of laser write for a line of laser scanning to compensate the image to be formed using the movable mirror.

摘要： In an image forming apparatus which forms an image by transferring, onto sheets fed by a feeding unit at the first feeding interval, a toner image formed on a photoconductor or intermediate transfer member, if the temperature of a fixing unit which fixes an image transferred onto a sheet falls outside a set temperature range, the sheet layout is changed to a feeding interval wider than the first feeding interval. Whether to perform adjustment processing is determined based on determination of an image forming condition. If the feeding interval is changed to a wider one in the feeding interval changing step during image formation and it is determined in the determination step to perform adjustment processing, toner patch images are formed in an area where no toner image is formed on the photoconductor or intermediate transfer member. The adjustment processing is performed based on reading toner patch images.
