Abstract
In a transfer-type electronic copying machine including a photosensitive drum, charging device, exposure device, developing device, transfer device, and separating device, the separating device of this invention has a separating section for separating a recording sheet bearing a toner image thereon from the surface of the photosensitive drum. The recording sheet is guided by a guide roller facing the photosensitive drum and having a slit formed therein, and is brought in contact with a conductive brush through the slit to be de-electrified.
Claims5
A separating device for use in a transfer-type copying machine for separating a recording sheet from a surface of a photosensitive member after a developed image on the surface of the photosensitive member has been transferred to the recording sheet at an image transfer station, said separating device comprising:
- (a) separating means for separating the recording sheet bearing a toner image thereon from the surface of said photosensitive member;
- (b) guide means, facing said photosensitive member and having at least one opening, for supporting the separated recording sheet;
- and
- (c) de-electrifying means, separate from said guide means, for de-electrifying said recording sheet through said opening, said guide means maintaining constant the distance between said recording sheet and said de-electrifying means.
