METHOD FOR INSPECTING ELECTROPHOTOGRAPHIC SENSITIVE BODY AND APPARATUS USED IN SAID INSPECTION METHOD

摘要

PURPOSE:To enable easy discrimination of whether a defect exists or does not exist by cleaning the remaining toner on the surface of an amorphous silicon photosensitive body and impressing a high voltage thereto in contact therewith, then irradiating light to erase the memory, forming a transferred image on a material to be recorded and inspecting the transferred image. CONSTITUTION:The remaining toner on the photosensitive drum surface 1 after the process for forming an electrophotographic image is removed by a cleaning means 3 and the high voltage is impressed to the drum surface 1 by a conductive rubber roller 5 connected to a constant voltage power source 6. The photosensitive drum 1 is exposed again by an exposing means 4 to erase the residual potential. The spherical projections which are problematic on the a-Si photosensitive drum 1 surely develop the image defect to a sensible image in an image forming stage. The image having the image defect is formed if such electrophotographic image is formed. The photosensitive drum having the defect is thereby surely expelled prior to delivery.
