Electrophotographic image forming system with cleaning blade

An electrophotographic image forming system that forms an electrostatic latent image on at least a photoreceptor, develops an image using an electrostatic charge image developing toner, and removes the electrostatic charge image developing toner using a cleaning blade, a tip ridge of the cleaning blade being pressed against a surface of the photoreceptor, the electrophotographic image forming system comprising:

• a photoreceptor including a photosensitive layer,
• a surface protecting layer that is provided on a surface of the photosensitive layer,
• wherein 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) below, and
• 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°
• in General formula (1), Ar1 and Ar2 each represent a linking group represented by a structural formula (7) below;
• Ar5 represents a group represented by a structural formula (8) or a structural formula (9) below;
• the total number of D that is a sum of c1, c2, and c5 is 1 or 2 when Ar5 is represented by the structural formula (8);
• the total number of D is 1 when Ar5 is represented by the structural formula (9);
• D is represented by —(—(CH2)d—(O—(CH2)f—)e—O—CO—C(CH3)═CH2) or —(—(CH2)d—(O—(CH2)f—)e—O—CO—CH═CH2);
• d and f each independently represent an integer of 0 to 5;
• e represents 0 or 1;
• and c1, c2, and c5 each independently represent 0, 1, or 2,
• in the structural formulas (7), (8), and (9), R5 and R6 each independently represent one selected from a group consisting of a hydrogen atom, an alkyl group containing 1 to 4 carbon atoms, a phenyl group substituted with an alkoxy group having 1 to 4 carbon atoms, an unsubstituted phenyl group, an aralkyl group having 7 to 10 carbon atoms, and a halogen atom;
• t represents an integer of 1 to 3;
• and two of R6 may be optionally bonded together so that the structural formula (9) forms a cyclic structure.
