2. Description of the Related Art An electrophotographic photosensitive member is a main medium for forming an image in an electrophotographic process such as a copying machine, a laser beam printer, and a facsimile. The image forming process is usually a repetition of charging, exposure, development, transfer, cleaning and charge removal. More specifically, when an electrophotographic photosensitive member whose surface is uniformly charged by a corona electrode or a rubber electrode is image-exposed using halogen light or laser light, the charged potential of an exposed portion is attenuated, and an electrostatic latent image is formed. Is formed. Next, a visible image is formed on the electrophotographic photosensitive member by developing the electrostatic latent image using the charged toner as a developer. The visible image is transferred to the transfer material by the Coulomb force and the pressure by the transfer charging. At this time, it is difficult to transfer all the toner, and in order to use the photoconductor repeatedly, it is necessary to clean the residual toner on the photoconductor. Further, after cleaning, the charge history is eliminated by strong exposure, bias application, or the like, and the process proceeds to the next repetitive process.

[0003] Cleaning will be described in more detail. As means for removing fine particles such as toner from the surface of the photoreceptor, cleaning using a fur brush, a magnetic brush, a blade, or the like is known. In particular, blade cleaning is the most widely used cleaning method in recent years because of its high cleaning effect and simple configuration of the apparatus. The cleaning blade has a structure in which an elastic member blade 1 made of a plate-like polyurethane or the like is attached to a support 2 as shown in FIGS.
The photosensitive member is pressed and abutted in the longitudinal direction. As shown in FIG. 5, there are two directions in which the blade comes into contact with the photosensitive member 3 in a forward direction and a counter direction as shown in FIG. Is more preferred. In order to further improve the cleaning effect, it is preferable to increase the contact pressure of the blade 1 with the photoconductor 3.

Improving the above-mentioned cleaning effect is very important for maintaining image quality during repeated use, but has the disadvantage of increasing the frictional force generated between the photosensitive member and the blade. . In other words, an increase in the frictional force between the two causes an increase in the amount of scraping of the photoreceptor and the occurrence of flaws, thereby significantly reducing the life of the photoreceptor.

On the other hand, in recent years, the surface hardness of an electrophotographic photosensitive member using an organic photoconductive material, which has become a mainstream of the electrophotographic photosensitive member due to its advantages such as mass productivity, low cost, and no pollution, is as follows.
Generally lower than those using inorganic photoconductive materials,
An increase in the amount of surface scraping by the cleaning blade and the occurrence of scratches were likely to occur.
