ABSTRACT:
In association with a primary cleaner device, used to remove the preponderance of toner remaining on a charge retentive surface after transfer, a secondary cleaning member is provided, arranged for the removal of toner agglomerates formed by the agglomeration of toner, and toner and debris. The secondary cleaning member is characterized as a thin scraper member arranged at a low angle of attack with respect to the photoreceptor so that a maximum shearing force can be applied by the blade to the agglomerates for removal thereof. A relatively low load is applied to the blade, so that the problems associated with normal cleaning engagement of blades with a charge retentive surface are avoided.
