| 英文摘要 | PURPOSE:To obtain a clear print image having no fluctuation of tint by regulating the reference potential for controlling the quantities of light to be emitted from respective semiconductor lasers independently and commonly to respective semiconductor lasers. CONSTITUTION:Variable resistors R1-R3 constituting a first regulating means feed the referential potentials VS1-VS3 independently to respective comparators 11-13. A variable resistor R4 constituting a second regulating means regulates the reference potentials VS1-VS3 determined by the variable resistors R1-R3 variably and commonly. Comparators 11-13 compare an output potential from an optical detecting means 6 for detecting the laser beam sequentially corresponding to the quantity of laser beam emitted from respective semiconductor lasers 2-4 with respective referential potentials regulated variably by the first regulating means R1-R3 or the second regulating means R4, then laser drive control means 19-21 control the driving currents to be applied onto respective semiconductor lasers 2-4 according to the outputs from the comparators 11-13. Consequently, a constant picture quality can be obtained at all times against the fluctuated sensibility when replacing a photosensitive drum. |
