PROBLEM TO BE SOLVED: To make the surface state of an image carrier after cleaning different according to the presence or absence of the occurrence of connection failures of a cleaning part.SOLUTION: A printer includes a rotationally driven photoreceptive drum 28, a developing roller 25, etc., forming an image on the photoreceptive drum 28 with toner, a drum cleaning voltage generation circuit 52 outputting a drum cleaning voltage DCLN, and a drum cleaner 30A to which the drum cleaning voltage DCLN is applied to clean the photoreceptive drum 28. A control part 40 forms an inspection pattern image in a target area on the photoreceptive drum 28 and changes the drum cleaning voltage DCLN, while the target area in which the inspection pattern image is formed passes through a cleaning position XC. |
