Abstract
An apparatus for cleaning a photosensitive member of an electrostatic copying machine which includes neutralizing means electrically connected to the ground and disposed for contact with the surface of a photosensitive member in a region located between a transfer station where a toner image formed on photosensitive member is transferred onto a transfer sheet and a cleaning station where any residual toner remaining on the photosensitive member after the transfer step is removed. In this manner, the photosensitive member is neutralized after the transfer step before the residual toner is removed therefrom.
Claims18
An apparatus for cleaning a photosensitive member of an electrostatic machine forming visible images from a dry developer in which a toner image formed on the photosensitive member is transferred to a transfer sheet in a transfer station and any residual toner is removed in a cleaning station having an element adapted to engage said photosensitive member for removing residual toner therefrom;
- characterized by the provision of neutralizing means electrically grounded and disposed for contact with the surface of the photosensitive member in a region between the transfer station and the element of said cleaning station.
