英文摘要PURPOSE:To attain a stable gradation expression by detecting the density of a visual image developed on a sensitive body, which is a reference, and controlling a laser output to compensate the variation of the density. CONSTITUTION:The revealed picture, which is a reference, is formed on the sensitive drum 33 and the density is detected by a density sensor 27 in a proper before executing image formation. The detected value is composed with a prescribed value in a control part 14 and the contents of a buffer 18 which sets the laser output is corrected. Then, the laser modulation current value of a laser modulation circuit 30 is decided to obtain the laser output according to the prescribed value of the density. Therefore, the variation of the density of electrophotography sensitive body can be compensated and the stable gradation expression can be obtained.
