Abstract

An image forming apparatus has an image scanner, a sensor for determining that the image sensor has scanned the front edge of a document, and a controller using main scanning line synchronizing signals and an output signal of the sensor as reference signals. In response to the reference signals, the controller causes at least a writing unit to start writing each image data of particular color and causes a transfer medium driving circuit to start driving a transfer medium. The apparatus allows image components of different colors to be transferred to the transfer medium one above the other in accurate registration.
