PURPOSE:To extend the substantial life of a cleaning blade by constituting the cleaning blade so as to be released from the surface of a photosensitive body. CONSTITUTION:When the form end is detected by a form end detecting mechanism 15, a rotary solenoid 9 is conducted to rotate an arm shaft 8 provided with a cleaning blade 2, and contact with a spring member 10. The arm shaft 8 contacting with the spring member 10 vibrates to separate a residual toner, etc. attaching to the cleaning blade 2 from the cleaning blade 2, and drop to a carrying means 5. On the other hand, the residual toner, etc. attaching to the surface of a photosensitive body 1 is scraped down by an auxiliary blade 12 attached to the end part of a cleaning device to drop to the carrying means 5, and the toner collected by a feed screw 5a is fed to a developing device 14 or collected in a collecting box to throw away. |
