Abstract: Disclosed is a toner for electrostatic image development that satisfies both low-temperature fixing ability and excellent high-temperature storage stability, achieves excellent charge property and shatter resistance, and consequently can form a high-quality image even by a high-performance machine such as a high-speed machine.The toner is composed of toner particles obtained by forming a shell layer containing a styrene-acryl-modified polyester resin on the surface of each of core particles comprising a binder resin containing at least a styrene-acrylic resin. The styrene-acryl-modified polyester resin is obtained bonding a styrene-acrylic polymer segment to a terminal of a polyester segment, and the content of the styrene-acrylic polymer segment in the styrene-acryl-modified polyester resin is 5% by mass or more and 30% by mass or less.

Abstract: An electrophotographic image forming method is disclosed. A latent image on a photoreceptor is developed to form a toner image on the photoreceptor by a developer and the toner image is transferred to a recording material or an intermediate transfer element, and the developing and the transferring are performed while regulating a contact angle of the photoreceptor with water within ±5° of an average contact angle by applying a surface energy-lowering agent on the surface of the photoreceptor.
