(57) Abstract: Provided is a toner capable of obtaining a stable image with high image density, low fog, and irrespective of environmental changes, and an image forming method, an image forming apparatus, and a process cartridge using the toner. I do. SOLUTION: The toner has at least a binder resin, a colorant, and toner particles containing a sulfoalkylacrylic acid-based copolymer and an inorganic fine powder, has an average circularity of 0.960 or more, and has a sulfoalkylacrylic acid. The copolymer is a copolymer of a sulfoalkylacrylic acid monomer represented by the general formula (1) or (2) and another vinyl monomer copolymerizable therewith. The monomer composition ratio of this copolymer is such that the sulfoalkylacrylic acid monomer is 0.1 to 2 0% by mass, and other vinyl monomers are 80 to 99.9. The toner is used in an image forming method by mass%. |
