PURPOSE:To hold a stable cleaning effect, by performing the discharging of 1- 5X10<-8>C/cm.sec with a different polarity by corona discharge before particles stuck onto a electrified fibrous member are removed by a removing member. CONSTITUTION:A residual toner T1 on a photosensitive drum 1 is stuck to brush hairs 2 by frictional electrification and a stuck toner T2 is attracted to a removing member 4, which is biased with a polarity opposite to that of a toner T2, electrostatically and is transferred to the surface of the brush hairs 2, and a transferred toner T3 is removed from the removing member 4 by a blade 5 or the like. In this case, since the toner T2 cannot be transferred efficiently to the removing member 4 to cause various troubles if brush hairs 2 are electrified strongly, 1-5X10<-8>C/cm.sec electric quantity with the opposite polarity is given to brush hairs 2 for the purpose of making the electrification quantity of brush hairs 2, to which the toner T2 is stuck, most suitable pertinently. |
