| 英文摘要 | PURPOSE:To attain a stable gradation expression by detecting the electric potential of a bright part formed on a sensitive body and controlling a laser output so as to compensate the variation of the sensitivity of the sensitive body. CONSTITUTION:The electric potential of the bright part formed on the sensitive drum 23 is detected by lighting a laser by an electric potential sensor 27 and the detected value and a prescribed value are compared in a control part 14. And the contents of a buffer 18 which sets the laser output is corrected. Thus, the laser modulation current value of a laser modulation circuit 30 is decided to obtain the laser output according to the specified electric potential value of the bright part. Therefore, the variation of the sensitivity of an electrophotography sensitive body can be compensated and the stable gradation expression can be attained. |
