摘要： An image forming apparatus includes: a photosensitive member; a developing roller; a contact/separation mechanism configured to switch between a contact state in which the developing roller is brought into contact with the photosensitive member and a separation state in which the developing roller is separated from the photosensitive member; a photosensitive-member motor configured to rotate and drive the photosensitive member; and a control portion. The control portion configured to determine that the contact/separation mechanism is in a failure state in a case where a torque of the photosensitive-member motor is not detected to have changed by at least a predetermined value within a predetermined time after a predetermined reference timing.

摘要： An image forming apparatus includes an image forming unit and a developing separation mechanism. The image forming unit includes an image carrier and a developing device. The developing device includes a developing member and movable in a developing position where the developing member is in contact with the image carrier and a separated position where the developing member is separated away from the image carrier, and is configured to be drawn out from an apparatus main body. The developing separation mechanism includes an arm member configured to interfere with the developing device from a downstream side of a draw-out direction so as to move the developing device from the developing position to the separated position, and to be turned to an upstream side of the draw-out direction by the image forming unit when the image forming unit is drawn out and then be separated from the developing device.

摘要： With a cleaning system/method, a user places a printing device in a cleaning mode, inserts a cleaning apparatus that includes a cleaning sheet into a paper supply tray of the printing device, and executes a cleaning operation on the printing device. With the system, a set of instructions is stored on a machine-readable medium. The set of instructions causes the printing device to execute a cleaning operation on a feed nip of the printing device. The cleaning sheet cleans the feed roller and the retard roller when it is positioned within the feed nip during the cleaning operation. The set of instructions cause the printing device to move the cleaning sheet into the feed nip and to rotate the feed roller and the retard roller for a predetermined time period, when the printing device is placed into a cleaning mode.
