    Abstract: Provided is a toner for electrostatic image development that has good low-temperature fixability, also has long-term heat-resistant storage stability and can form an image with unevenness in gloss suppressed. The toner for electrostatic image development includes toner particles. The toner particles have a domain-matrix structure in which a first domain phase including a crystalline polyester resin A and a second domain phase including a crystalline polyester resin B are dispersed in a matrix phase including a vinyl resin. The average diameter of the first domain phase is 400 to 900 nm, and the average diameter of the second domain phase is 10 to 200 nm. The melting point of the crystalline polyester resin A and the melting point of the crystalline polyester resin B are each 95° C. or lower.

    Abstract: 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°.
