Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To use photosensitive drum up to the limit, and to realize miniaturization of a cleaning device by providing a detecting section detecting waste toner quantity, and remove-storing means storing on removing the waste toner when removing means are apart from the photosensitive drum. SOLUTION: After transferring, when the detecting section 8 detects that the waste toner in the storage chamber 4 reaches a prescribed quantity, removing means 3 part from a surface of the photosensitive drum 1. In this way, the waste toner is carried to a site of temporarily storing means 7 while remaining intact on the surface of the photosensitive drum 1. The waste toner is stripped from the photosensitive drum surface by the temporarily storing means 7 while temporarily stored. After completion of recording, the waste toner is discharged from the temporarily storing means 7, and returned to the storage chamber 2.  Then, since the temporarily storing means are used only after the storage chamber 2 achieves the prescribed quantity, the life of the temporarily storage chamber 5 can be extended longer than the photosensitive drum service life, as a result the photosensitive drum 1 can be made full use until the life.
