ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18306431 titled 'ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC APPARATUS
Simplified Explanation
The patent application describes an electrophotographic photosensitive member, which is a component used in printers and photocopiers.
- The photosensitive member consists of a cylindrical support and a photosensitive layer.
- The surface of the support is made of aluminum (Al) or an aluminum alloy.
- The surface of the support contains Al crystal grains with specific orientations.
- The Al crystal grains have planes oriented at certain angles with respect to {001}, {101}, and {111} orientations.
- The ratio of the area occupied by Al crystal grains with {101} orientation to the total surface area is 10% or less.
- The ratio of the area occupied by Al crystal grains with {111} orientation to the total surface area is more than 10%.
Original Abstract Submitted
Provided is an electrophotographic photosensitive member including: a support having a cylindrical shape; and a photosensitive layer, wherein the support has a surface formed of Al and/or an Al alloy, the surface of the support includes Al crystal grains having: (α) a plane at −15° or more and less than +15° with respect to a {001} orientation; (β) a plane at −15° or more and less than +15° with respect to a {101} orientation; and (γ) a plane at −15° or more and less than +15° with respect to a {111} orientation, a ratio of an area occupied by the Al crystal grain having the (β) to a total area of the surface of the support is 10% or less, and a ratio of an area occupied by the Al crystal grain having the (γ) to the total area of the surface of the support is more than 10%.
