A light scanning controller includes a plurality of light scanning parts for forming a latent image on a photoconductor by irradiating it with a scanning laser beam, and a clock controller for generating a timing signal by using a single clock signal obtained from a master clock oscillator to transmit the timing signal to each of the light scanning parts which controls the timing of the scanning laser beam on the basis of the timing signal received from the clock controller.

Image forming apparatus with a plurality of image forming units

A pair of feed rollers for sending an ink ribbon into a ribbon case have a number of grooves on the circumferential faces thereof such that opposed grooves do not mesh with each other. A heater is disposed in a travel path for the ink ribbon, for heating the ink ribbon to prevent deterioration of the drawability of the ink ribbon drawn by the pair of feed rollers.
