摘要	PURPOSE:To obtain a color print with always proper color arrangement by measuring the surface potential values of photosensitive bodies corresponding to optical beams and adjusting respective optical beams so that the deviation of respective surface potential values is included within a previously set range. CONSTITUTION:Semiconductor laser driving circuits 41A-41D modulate semiconductor lasers 31A-31D in accordance with a video signal sent from a storage part 35 and respective optical beams are supplied to the photosensitive drums 18A-18D as recording information. The surface potential values of these drums 18A-18D are measured by surface potential measuring instruments 30A-30D. Measured result output signals respectively obtained from the measuring instruments 30A-30D are fed back to the circuits 41A-41D through a light intensity stabilizing signal generating circuit 45. When a specific one out of four measured result output signals is set up as a reference, the circuit 45 generates the light intensity stabilizing signal for including the deviation of other three output signals within the previously set range and outputs the signal to the circuits 41A-41D. Consequently, the light intensity of the four light beams are adjusted so as to be the same.
其他摘要	目的：通过测量对应于光束的感光体的表面电位值并调节各个光束，使得各个表面电位值的偏差包括在预先设定的范围内，以获得总是具有适当颜色排列的彩色印刷品。组成：半导体激光器驱动电路41A-41D根据从存储部分35发送的视频信号调制半导体激光器31A-31D，并且各个光束作为记录信息提供给感光鼓18A-18D。这些鼓18A-18D的表面电位值由表面电位测量仪器30A-30D测量。分别从测量仪器30A-30D获得的测量结果输出信号通过光强度稳定信号发生电路45反馈到电路41A-41D。当四个测量结果输出信号中的特定一个被设置为参考时，电路45产生光强度稳定信号，用于将其它三个输出信号的偏差包括在预先设定的范围内，并将该信号输出到电路41A-41D。因此，调整四个光束的光强度以使其相同。
