Abstract
Provided is an electrophotographic photosensitive member which is excellent in terms of both continuous reduction of contact stress with contact members and the like and potential stability during repeated use. A charge transport layer which serves as a surface layer of an electrophotographic photosensitive member has a matrix-domain structure including a matrix containing a component [β] (polycarbonate resin D having a specific repeating structural unit) and a charge-transporting substance and domains containing a component [α] (polycarbonate resin A having a repeating structural unit including a specific siloxane moiety).
