摘要： An electrophotographic toner comprising a constituent resin and a colorant, in which the constituent resin has a softening point ranging from room temperature to 170.degree. C. and comprises (a) a copolymer of cinnamic acid and one or more vinyl monomers, (b) a mixture of a copolymer as defined in (a) and a polymer having good compatibility therewith, (c) a mixture of a copolymer as defined in (a) and cinnamic acid, (d) a mixture of a polymer as defined in (b) and cinnamic acid, or (e) a mixture of a mixture as defined in (b) and cinnamic acid, the cinnamic acid content of the constituent resin being from 1 to 25 parts by weight per 100 parts by weight of the constituent resin in the case of cinnamic acid copolymerized with one or more vinyl monomers and from 0.1 to 25 parts by weight per 100 parts by weight of the constituent resin in the case of cinnamic acid present in the uncombined state.
