Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/067853
Kind Code:
A1
Abstract:
Provided are an electrophotographic photoreceptor which is excellent in a cleaning performance and a process cartridge and an electrophotographic device which have the electrophotographic photoreceptor.
On the peripheral surface of the electrophotographic photoreceptor, a plurality of flat portions each having a width e (µm) of 0.1 ≤ e ≤ 25 and a plurality of groove portions each having a width w (µm) of 0.1 ≤ w ≤ 25 and a depth d (µm) of 0.1 ≤ d ≤ 3.0 are alternately formed so as to form an angle θ (º) of 80 ≤ θ ≤ 100 with respect to the axis direction of the electrophotographic photoreceptor. The sum eSum (µm) of the widths e of the flat portions per 100-µm width of the peripheral surface in the axis direction satisfies 5 ≤ eSum ≤ 75, and in the case where the average value of the widths e of the flat portions is represented by eAv (µm) and the standard variation thereof is represented by eσ, eσ/eAv satisfies eσ/eAv ≤ 0.46.
