ABSTRACT:
Highly efficient, long life blade cleaning apparatus for removing residual toner particles from a flexible photoreceptor supported for movement in an endless path. The cleaning blade is supported for pressure engagement with a flexible belt such that the belt is deflected. A backing member is supported in contact with the reverse side of the belt for controlling the degree of belt deflection and thereby the force required by the blade for efficient cleaning to a minimum and effect substantially uniform contact between the blade and the charge retentive member. The support is positioned downstream of the blade a predetermined distance which minimizes the required cleaning force and also allows the belt to twist to thereby conform to the blade edge resulting in substantially uniform contact between the blade and belt.
