Abstract
Official abstract text for this publication.
A charge-transporting layer, which is a surface layer of an electrophotographic photosensitive member, has a matrix-domain structure having a matrix containing constituent β (a polyester resin having a predetermined repeating structural unit) and a charge-transporting substance, and a domain containing constituent α (a polycarbonate resin having a repeating structural unit having a predetermined siloxane moiety).
First claim
Opening claim text (preview).
The invention claimed is: 1. An electrophotographic photosensitive member, comprising: a support, a charge-generating layer which is provided on the support and comprises a charge-generating substance, and a charge-transporting layer which is provided on the charge-generating layer and is a surface layer of the electrophotographic photosensitive member; wherein the charge-transporting layer has a matrix-domain structure having: a domain which comprises the constituent α, a…
