Title: Method for cleaning
Inventor: YOSHIDA NORITOSHI
IPC: G03G21/10
Filed: 1980-09-12
Abstract: PURPOSE:To minimize a web consumption and to extend the life of the image carrier without deteriorating the cleaning performance, by moving the web only for the period which remaining toner exists on the surface of the image carrier after images are transferred. CONSTITUTION:A cleaning web 3 moves while it is tightly contacted the surface of a photosensitive drum so that the web will shave off materials adhered on the drum. In this invented cleaning method, the web is operated by transmitting the drive to a web winding roller only the time when a developed area comes to the cleaning section. To realize this arrangement, a magnetic clutch is used and the web is operated by turning on the clutch when an area developed by toner comes to the cleaning equipment and by truning off the clutch when the developed area has passed the cleaning equipment. In this way, the web consumption is reduced to about 1/5 as much as that of conventional method when only one copy is made, and the durability of the photosensitive drum against abrasion is extended.
