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 tone, 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. The blade is supported in a floating support assembly, that floats during break in of a new blade to prevent tuckunder and damage to the blade. The weight of the floating support assembly is optimized for the break in period when frictional forces are the highest. The assembly is loaded with a weight selected to maintanin the blade in contact wiht the charge retentive surface. A stop is provided at the floating blade support which limits the range of movement of the floating blade, so that creep is prevented in normal operation.
