    摘要： A laser driving method is adapted for driving a plurality of laser emitting devices. A first current to be supplied to each of the plurality of laser emitting devices is always generated. A plurality of second currents controlled according to a control signal supplied from the outside are generated when necessary. The plurality of second currents are supplied to the respective laser emitting devices under supply of the respective first currents, thereby making the laser emitting devices emit respective laser beams. The plurality of laser emitting devices are caused to emit the laser beams in time division at predetermined timing to detect each of emitted light amounts by one laser monitor. Adjustment is made to at least one of the first current and the second current supplied to each of the laser emitting devices according to a plurality of detected light amounts detected. Supply of the current to the laser emitting devices not driven is stopped when the plurality of laser emitting devices are adjusted in light amount in time division.

    摘要： An image forming apparatus is arranged to form an image with laser light emitted from a semiconductor laser source, and is constructed so as to protect the laser source from a breakdown, by regulating electric current flowing to the laser source no matter when an adjusting circuit for adjusting the light amount of the semiconductor laser source is apt to supply the electric current that could break the laser source, to the laser source. The apparatus is constructed in such structure that during an automatic light amount control period the laser light amount emitted from the semiconductor laser source is detected and a current source circuit is made inactive when the light amount detected is over a set light amount and that during periods other than the control period the electric current flowing to the semiconductor laser is detected and the current source circuit is made inactive when the light amount detected becomes over a fixed ratio times the current detected during the automatic light amount control period. In this way, the protection circuit can operate effectively anytime of emission of the laser source, so as to protect the laser source from the breakdown.
