摘要： An image forming apparatus which has a plurality of image forming stations arranged in parallel, each of the image forming stations having a photosensitive drum, and which forms a desired image by combining toner images formed on the photosensitive drums. A laser scanning optical system deflects and scans a plurality of laser beams concurrently with a single polygon mirror to irradiate the photosensitive drums. In a monochromatic mode, the rotation speed of the photosensitive drum for forming a black image is changed higher, and synchronization of writing in a main scanning direction is performed by using one of the laser beams irradiating the other photosensitive drums of which rotation speeds are not changed.

摘要： In an image forming apparatus employing a multi-beam method, the total emission period of time is stored for each laser beam. In accordance with the total emission periods of the laser beams, the laser beam used for SOS is switched, so that the total emission periods are kept almost equal to each other. When the laser beam used for the SOS is switched, the adjustment processing for correcting misalignment of the laser beams in the main scanning direction is changed in accordance with the current laser beam used for the SOS, and the emitting order of the laser beams for the APC is also accordingly changed.
