摘要：
In the printing apparatus wherein the laser diode is used as light source for writing images on an image carrier, a control transistor is serially connected to the laser diode. The magnitude of the drive current for driving the laser diode is adjusted in accordance with the magnitude of the base current of the control transistor. The base current of the control transistor is turned on when the main power supply is implemented. That is, the control transistor is pre-heated up to print command. Consequently, the drive current is stable from the initial image formation after the main power supply is turned on.
