Abstract

A method and apparatus for controlling an optical printer where respective light emitting elements are energized for light emission based on one line amount of received image data for a time equal to an ON time of a strobe signal thereby to form an image on a photosensitive member. The strobe signal is selected from a group consisting of a predetermined number of base signals each having a different ON time and one or a plurality of composite signals each composed of a different combination of the base signals. The one line amount of image data are outputted for a number of times equal to the number of base signals, within a time allotted for one line amount of exposure. The light emitting elements corresponding to the image data are energized for light emission for a time equal to the ON time of the selected strobe signal.
