摘要： A polygonal mirror is rotated by a brush motor, and a laser beam deflected by the polygonal mirror is detected by a sensor for generating a signal which determines a printing start position of each scanning line. The rotating speed of the motor is proportional to the frequency of the signal, and when the frequency of the signal becomes equal to a reference value, the motor can be judged to come to a steady rotation state. In a control circuit, the rotating speed of the motor is detected from the frequency of the signal, and the difference between the detected speed and a reference value is calculated and is sent to a comparator. Based on the speed difference and the back electromotive force which occurs in the motor, the comparator controls the driving voltage of the motor.

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.

摘要： An image forming apparatus having a quantum-well semiconductor laser as a light source, a photosensitive member and an optical system for transmitting a laser beam emitted from said quantum-well semiconductor laser to the photosensitive member. The optical system has a reduced transmittance to suppress variations in the laser beam intensity within an allowable range. The transmittance of the optical system is adjusted by providing a reflecting coating on the beam emitting surface of the quantum-well semiconductor laser.
