The present invention provides a toner and a developer having low-temperature fixability, hot offset resistance, heat-resistant storage stability, excellent antifouling property, and stable image density that can be applied to an ultrahigh-speed image forming system. A divalent alcohol comprising a divalent alcohol compound-containing alcohol component, a polyester resin (A) obtained from a rosin compound-containing carboxylic acid component, and an alkylene oxide adduct of a bisphenol compound represented by a specific formula. A toner is obtained with a binder resin, a colorant, a release agent, and a graft polymer mainly composed of a polyester resin (B) obtained from a compound-containing alcohol component and a carboxylic acid component as a developer. This is used for an image forming method and a process cartridge of an ultra high speed image forming system. [Selection] Figure 1 |
