Abstract

A flexible belt photoreceptor in an electrophotographic device may be provided with a cleaning blade for the removal of residual toner and debris from the belt photoreceptor. As described in United States Patent No. 4,630,920 to Silverberg et al., a backing member may be supported in contact with the reverse side of the photoreceptor belt for controlling the degree of belt deflection, and thereby the force required by the blade for efficient cleaning, and to maintain substantially uniform contact between the the blade and the photoreceptor belt. Other arrangements may provide back up rolls for the same purpose.

A flexible belt photoreceptor in an electrophotographic device may be provided with a cleaning blade for the removal of residual toner and debris from the belt photoreceptor. As described in United States Patent No. 4,630,920 to Silverberg et al., a backing member may be supported in contact with the reverse side of the photoreceptor belt for controlling the degree of belt deflection, and thereby the force required by the blade for efficient cleaning, and to maintain substantially uniform contact between the the blade and the photoreceptor belt. Other arrangements may provide back up rolls for the same purpose.

In accordance with the present proposal, a resilient back-up member is provided with a stiffly resilient, low friction blade arranged in a position on the opposite side of the photoreceptor belt, directly opposing the cleaning blade member. The back-up blade may be bowed and extend in the direction of photoreceptor travel, in wiping engagement therewith. The arrangement advantageously provides a compliant, planar-like support, which limits the normal cleaning force. The advantage of the arrangement is that it enables the contact between particles trapped between the cleaning blade and the photoreceptor to be more elastic, thereby limiting mechanical adherence of these particles to the belt photoreceptor to reduce cometin...
