Abstract
In an electrophotographic copying apparatus of the image transfer type, an image transfer device comprises a rotatable transfer member for urging and transporting an image transfer medium to an electrophotographic photosensitive medium to transfer the image of the photosensitive medium to the transfer medium, a cleaning blade urged into contact with the surface of the rotatable transfer member to clean the same to remove any contaminant adhering thereto, and means for urging and holding the cleaning blade against the surface of the rotatable transfer member. The cleaning blade may also be arranged to clean the surface of the photosensitive medium in a similar manner.
Claims12
Apparatus comprising a movable supporting member having contaminating matter disposed on a surface thereof, and a cleaning device for removing said contamination matter from said surface, said cleaning device comprising:
- an elongated blade of resilient material, said blade having two surfaces meeting to form an extended wiping edge;
- and
- resilient mounting means disposed adjacent said supporting member for maintaining the wiping edge of said blade in pressure contact with said supporting member surface, said resilient mounting means having said blade connected at one end thereof so that one of said two surfaces of said blade generally faces the other end of said mounting means, and so that the other of said two surfaces of said blade generally faces said supporting member and extends from its said contact position in the downstream direction with respect to the direction of movement of said supporting member, said mounting means having its said other end secured at a position located upstream from said contact position of said wiping edge.
