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.
