Abstract:
In an image forming apparatus that forms a color image by transferring toner images for respective colors formed on plural rotary photoreceptor drums onto a sheet through an intermediate transfer member, when a controller judges that magnification deviation is generated in a main-scanning direction in superposition of the toner images for respective colors, the controller forms a first color registration deviation detecting mark for detecting at least an amount of deviation in the main scanning direction on the intermediate transfer member, and when the controller judges that the magnification deviation is not generated in the main-scanning direction in the superposition of toner images for respective colors, the controller forms a second color registration deviation detecting mark for detecting only an amount of deviation in a sub scanning direction perpendicular to the main-scanning direction on the intermediate transfer member.
