Abstract:
1. A write control circuit for controlling a plurality of laser diode driver circuits that respectively drive a plurality of laser diodes each emitting light, the write control circuit comprising: a plurality of write control parts mounted on a single semiconductor chip and configured to control the plurality of laser diodes via the plurality of laser diode driver circuits to perform writing for image forming with a plurality of respective colors, wherein each of the plurality of write control parts includes at least one image development part configured to develop and process image data and at least one laser diode control part configured to control driving of the laser diodes via the laser diode driver circuits based on the image data; and a switch provided between a group of the image development parts and a group of the laser diode control parts of the plurality of write control parts and configured to switch connections between the image development parts and the laser diode control parts such that the number of the laser diode control parts connected to one of the image developing parts is changed.
