Title:
電子写真感光体、プロセスカートリッジおよび電子写真装置
Document Type and Number:
Japanese Patent JP6850205
Kind Code:
B2
Abstract:
Provided is an electrophotographic photosensitive member capable of achieving both high leak resistance and reduction in variations in dark part potential and bright part potential due to repeated use even when CB is used for an electrically conductive layer. An electrophotographic photosensitive member including: a support, an electrically conductive layer, and a photosensitive layer, sequentially, wherein the electrically conductive layer contains a binder resin and carbon black, a number average primary particle diameter of the carbon black is 200 nm or more and 500 nm or less, an average inter-particle distance of the carbon black is 200 nm or more and 600 nm or less, a coefficient of variation of an inter-particle distance is 1.2 or less, and SF-1 of the carbon black is 150 or less.
