Abstract
An image controller of an image forming apparatus is configured to generate a light emission signal for detection for forming light emission for detection, and transmit the light emission signal for detection to a laser controller through a flexible flat cable, and the laser controller is configured to cause a semiconductor laser to emit light in accordance with the light emission signal for detection, and determine, based on a PD signal output from a PD that has received a light beam, whether improper connection has occurred in the flexible flat cable.
