Title:
クリーニングブラシのブラシ密度と静電像の1画素面積の設定方法
Document Type and Number:
Japanese Patent JP4546055
Kind Code:
B2
Abstract:
An electrophotographic apparatus comprises a photosensitive member (2) comprising a surface layer and a photosensitive layer, an exposing mechanism, developing mechanism, and a cleaning device for cleaning a residual developer from the photosensitive member after the developer image is transferred to an image receiving member. The cleaning device comprises a cleaning brush (8d) brought into contact with the photosensitive member. An electrophotographic apparatus comprises: (a) a photosensitive member comprising a surface layer formed on its surface, and a photosensitive layer, a sum of a thickness of the photosensitive layer and the surface being = 25 Microm; (b) an exposing mechanism for exposing the photosensitive member in accordance with a digital image signal to form an electrostatic image on the photosensitive member; (c) a developing mechanism for forming a developer image on the photosensitive member by developing the electrostatic image by a developer; and (d) a cleaning device for cleaning a residual developer from the photosensitive member after the developer image is transferred to an image receiving member, which comprises a cleaning brush brought into contact with the photosensitive member. If the brush density of the cleaning brush is D (number/mm 2>), and the area of the pixels of the electrostatic image is S (mm 2>/dot), then D X S >= 0.06 and D =200, are satisfied.
