  • Patent number: 5812174
    Abstract: An apparatus has a plurality of semiconductor cells as current switchings for driving a laser diode which exposes to light a photosensitive member so as to effect image recording. The semiconductor cells have each different characteristics, or same characteristics respectively. In response to the light amount signal corresponding to light quantity of the laser diode, a selector selects one or more of the semiconductor cells so as to supply a suitable driving current turned on or off later with an image signal. As a result, no fluctuations in the pulse duty ratio and the rise time are present in the entire driving current active range, thus improving the quality of a recorded image. The effect of selection by the selector is held for a certain recording time, whereby malfunction due to noises or the like can be avoided, and stable actions of the laser diode are ensured.
