Abstract

PURPOSE: To achieve the improvement in the effect of cleaning by disposing a non- magnetic sleeve which is built in with a rotatable magnetrol and a porous elastic roll in the specified relation.
CONSTITUTION: Untransferred residual toner 9 while remaining deposited on the surface of a drum 1 approaches to a non-magnetic sleeve 11 which is built in with a magnetrol 10. Part of this residual toner 9 is attracted onto the non-magnetic sleeve 11 by the magnetic attraction force of the magnet roll 10 but the greater part thereof goes to the contact point of the elastic roll 15 comprising securing an elastic body 13 composed of porous material such as sponge rubber or the like to a shaft 14. This elastic roll 15 is contact moved in the direction opposite from the moving direction of the drum 1 and its moving speed is made about 1W2 times the peripheral speed of the drum 1. In this way, the toner transferred to the elastic roll 15 is sucked to the non-magnetic sleeve 11 and is thereby moved and rides on a scraper 17, from where it falls into a recovery box 18. In this way the efficiency of cleaning may be improved.
