ABSTRACT:
An image forming apparatus includes a device for forming an image; a device for detecting information relating to the image formed by the image forming device and for repeating the detection; and a device for determining a timing at which the detection is repeated by the detecting device on the basis of the information detected by the detecting device. A device for generating a pattern signal corresponding to a predetermined pattern for detecting the amount of registration deviation by the detecting device is also provided. In addition, a transport belt for transporting the recording medium through the plurality of image forming units is provided so that the image forming units also form predetermined images on the transport belt. A device is also provided for mechanically and/or electrically correcting registration in the image forming units on the basis of the amount of registration deviation detected by the detecting device.
