Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR
Document Type and Number:
Japanese Patent JP2012123238
Kind Code:
A
Abstract:

To provide a photoreceptor having a small change amount of a surface potential even in repeated use, having no moisture memory phenomenon, and having high sensitivity and high durability with wear resistance.

The electrophotographic photoreceptor comprises at least a photosensitive layer and a protective layer, successively layered on a conductive support. The protective layer contains a polymerization product produced by using a compound (A) having 7 or more polymerizable functional groups, a compound (B) having 2 to 4 polymerizable functional groups and surface-treated metal oxide fine particles which are surface-treated with a surface treating agent having a polymerizable functional group. The photosensitive layer contains an adduct of butane diol and titanyl phthalocyanine. In the reflection spectrum of the photosensitive layer, a ratio of the reflectance at 700 nm to the reflectance at 780 nm is 0.8 or more and 1.3 or less.
