ELECTROPHOTOGRAPHIC IMAGE FORMING SYSTEM
An electrophotographic image forming system forms an electrostatic latent image on at least a photoreceptor, develops an image using an electrostatic charge image developing toner, and removes the toner using a cleaning blade. A tip ridge of the cleaning blade is pressed against a surface of the photoreceptor. The system includes a photosensitive layer of the photoreceptor and a surface protecting layer that is provided on a surface of the photosensitive layer. The surface protecting layer includes a polymerizable monomer having at least two polymerizable groups in a molecule and a polymer of a hole transporting compound having a polymerizable group represented by General formula (1). The tip ridge of the cleaning blade has an edge angle that is obtuse and less than 120° and is pressed against the surface of the photoreceptor at an effective contact angle that is in a range of 8 to 20°.

IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD
An image forming apparatus includes an RFID tag reader, an image forming unit, and a processor. The RFID tag reader is configured to read information from an RFID tag on a sheet conveyed along a conveyance path. The image forming unit includes a developer carrier. The processor is configured to determine, based on information read from the RFID tag on the sheet, whether information written to the RFID is correct. The processor is configured to cause the sheet to be conveyed to the image forming unit, a developer image already formed on the developer carrier to be removed without printing of the developer image on the sheet, and then print an alternative toner image indicative of a tag writing error on the sheet using the developer carrier.
IMAGE FORMING APPARATUS AND PROCESS CARTRIDGE
An image forming apparatus includes an electrophotographic photoreceptor that has a photosensitive layer constituting a surface of the electrophotographic photoreceptor, a charging device that charges the surface of the electrophotographic photoreceptor, an electrostatic charge image forming device that forms an electrostatic charge image on the charged surface of the electrophotographic photoreceptor, a developing device that accommodates a developer containing a toner which contains toner particles and an external additive, and develops the electrostatic charge image formed on the surface of the electrophotographic photoreceptor by the developer as a toner image, a transfer device that transfers the toner image formed on the surface of the electrophotographic photoreceptor to a surface of a recording medium, and a cleaning device that includes a cleaning blade coming into contact with the surface of the electrophotographic photoreceptor and cleaning at least residual toner particles on the surface of the electrophotographic photoreceptor

POLYARYLATE RESIN AND ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER
A polyarylate resin includes repeating units represented by formulas (1), (2), (3), and (4). A percentage of the number of repeats of the repeating unit represented by formula (3) relative to the total number of repeats of the respective repeating units represented by formulas (1) and (3) is greater than 0% and less than 20%. In formula (1), R.sup.1 and R.sup.2 each represent, independently of one another, a hydrogen atom or a methyl group and X represents a divalent group represented by formula (X1) or (X2). In formula (2), W represents, a divalent group represented by formula (W1) or (W2).

Image forming apparatus
According to the embodiment, an image forming apparatus includes an image forming unit, a writing unit, and a processor. The processor forms a first image again on a third sheet, when the writing unit does not succeed in writing information in a wireless tag of a first sheet, on which the first image is formed by the image forming unit. Further, the processor discharges the third sheet prior to a second sheet, on which a second image is formed, the second image being next to the first image.
