摘要： A method monitors an electric current supplied to an electrostatic brush within a printing device. The electrostatic brush contacts and cleans a photoreceptor surface within the printing device. The method records a current spike pattern of when the electric current exceeds a first current threshold during the monitoring; however, the method will stop operations of the printing device if the electric current exceeds a second current threshold that is greater than the first current threshold. Further, the method can determine whether a scratch is present on the photoreceptor surface based on the current spike pattern.

摘要： A cleaning blade anti-peeling apparatus includes a transfer apparatus that transfers a toner image formed on an image carrier to an endless transfer member. An image carrier cleaning member captures toner remaining on the image carrier after the toner image is transferred. A cleaning recovery member recovers the toner on the image carrier cleaning member. A bias applying apparatus applies a bias voltage to move the toner of the image carrier cleaning member to the image carrier. An endless transfer member cleaning blade removes toner adhering to the endless transfer member after the toner image of the endless transfer member is transferred to a transfer material while abutting against the endless transfer member. The following relationship is satisfied: cleaning recovery member width
