Abstract:
Provided is an image-forming apparatus including: an electrophotographic photosensitive member including a support, a photosensitive layer, and a protective layer in the stated order; a charging unit; an exposing unit; a developing unit; a transferring unit; and a cleaning unit configured to clean off the toner, which remains on the electrophotographic photosensitive member after the transfer of the toner image from the electrophotographic photosensitive member by the transferring unit, with a cleaning blade, wherein the electrophotographic photosensitive member includes, on a surface thereof, a fatty acid metal salt-supplying unit configured to supply a fatty acid metal salt having 16 or more and 18 or less carbon atoms, and wherein the protective layer has a triphenylamine structure, one of an acryloyloxy group and a methacryloyloxy group, and a specific structure.

Claim (Index 1):
An image-forming apparatus comprising:\n an electrophotographic photosensitive member including a support, a photosensitive layer, and a protective layer in this order; a charging unit configured to charge the electrophotographic photosensitive member; an exposing unit configured to expose the electrophotographic photosensitive member to light to form an electrostatic latent image; a developing unit configured to develop the electrostatic latent image with a toner to form a toner image; a transferring unit configured to transfer the toner image from the electrophotographic photosensitive member onto a transfer material; and a cleaning unit configured to clean with a cleaning blade toner that remains on the electrophotographic photosensitive member after transferring the toner image from the electrophotographic photosensitive member by the transferring unit, wherein the electrophotographic photosensitive member includes, on a surface thereof, a fatty acid metal salt-supplying unit configured to supply a fatty acid metal salt having 16 to 18 carbon atoms, the protective layer comprises a triphenylamine structure, one of an acryloyloxy group and a methacryloyloxy group, and a structure represented by one of formulae (1) and (2): where at least two of R 1 , R 5  and R 9  represents a structure represented by formula (3), and each of the substituents except the substituents represented by formula (3) in R 1  to R 12  is a hydrogen atom or a methyl group; where at least two of R 21 , R 23  and R 25  represents a structure represented by formula (3), each of the substituents except the substituents represented by formula (3) in R 21  to R 26  is a hydrogen atom or a methyl group; where R 31  is a single bond or an optionally substituted methylene group, R 31  bonds to the ring in the cyclic structure represented by formulae (1) or (2), and * indicates a bonding site, a content of a structure represented by one of formulae (1\u2032) and (2\u2032) in the protective layer determined by pyrolysis gas chromatography-mass spectrometry is 10 to 20 mass % with respect to a total weight of the protective layer where at least two of R 1 , R 5  and R 9  represents a structure represented by formula (3\u2032), and each of the substituents except the substituents represented by formula (3\u2032) in R 1  to R 12  is a hydrogen atom or a methyl group; where at least two of R 21 , R 23  and R 25  represents a structure represented by formula (3\u2032), and each of the substituents except the substituents represented by formula (3\u2032) in R 21  to R 26  is a hydrogen atom or a methyl group\n \u2014R 31 \u2014NCO\u2003\u2003(3\u2032) \n where R 31  represents a single bond or an optionally substituted methylene group, and A is 0.020 to 0.075 when A=S1/S2 and S1 and S2 each represent a peak area of a spectrum obtained by subjecting a surface of the protective layer to measurement by a Fourier transform infrared spectroscopy total reflection method using Ge as an internal reflection element and a measurement condition of 45\u00b0 as an incident angle, when S1 is a peak area based on in-plane deformation vibration of a terminal olefin (CH 2 \u2550), and S2 is a peak area based on stretching vibration of C\u2550O.
