Abstract

A process for producing an electrophotographic photosensitive member. The electrophotographic photosensitive member includes a conductive support and a surface layer provided thereon containing at least a resin. The process has the step of forming a plurality of depressed portions on the surface layer by irradiation with laser light having a wavelength of 400 nm or less and having an output characteristic of a pulse width of 100 ns or less.

Claims

1. A process for producing an electrophotographic photosensitive member having on a conductive support a surface layer containing at least a resin and having depressed portions on the surface thereof, the depressed portions being free from berms at their rims,

the process comprising the step of forming the depressed portions by irradiation with excimer laser light having a wavelength of 400 nm or less and having an output characteristic of a pulse width of 100 ns or less.

2. The process for producing an electrophotographic photosensitive member of claim 8, wherein the step of forming the depressed portions by irradiation with excimer laser light having a wavelength of 400 nm or less and having an output characteristic of a pulse width of 100 ns or less provides depressed portions being free from berms at their rims to reduce friction between the electrophotographic photosensitive member and a cleaning blade.
