Abstract:
The present invention provides an electrophotographic photosensitive member sequentially including: a support; a photosensitive layer; and a protection layer formed on the support, wherein the protection layer has a triarylamine structure and a specific cyclic structure, and a specific A-value obtained by measurement using total reflection Fourier transform infrared spectroscopy is 0.010 or more and 0.050 or less.

Claim (Index 9):
A process cartridge detachably attachable to an electrophotographic apparatus main body, comprising:\n an electrophotographic photosensitive member; and at least one unit selected from the group consisting of a charging unit, a developing unit, a transfer unit, and a cleaning unit; the electrophotographic photosensitive member and the at least one unit being integrally supported, wherein the electrophotographic photosensitive member sequentially includes a support, a photosensitive layer, and a protection layer, the protection layer has a triarylamine structure and a cyclic structure represented by General Formula (1) or (2) below: (in General Formula (1), among R 1  to R 12 , at least two of R 1 , R 5 , and R 9  have a structure represented by General Formula (3) below, and the substituents except the substituents having the structure represented by General Formula (3) in R 1  to R 12  are a hydrogen atom or a methyl group), (in General Formula (2), among R 21  to R 26 , at least two of R 21 , R 23 , and R 25  have a structure represented by General Formula (3) below, and the substituents except the substituents having the structure represented by General Formula (3) in R 21  to R 26  are a hydrogen atom or a methyl group), (in General Formula (3), R 31  is a single bond or a methylene group that may have a substituent, R 31  bonds to the ring in the cyclic structure represented by General Formula (1) or (2), and * indicates bonding site), and an A-value represented by Equation (4) below is 0.010 or more and 0.050 or less,\n A=S 1/ S 2\u2003\u2003Equation (4) \n (in Equation (4), S1 is a peak area based on in-plane deformation vibration of a terminal olefin (CH2=) and S2 is a peak area based on C\u2550O stretching vibration among peak areas of spectrum obtained by measuring a surface of a protection layer by total reflection Fourier transform infrared spectroscopy using Ge as an internal reflection element and a measurement condition of an incident angle of 45\u00b0).
