PURPOSE:To enhance low temperature fixability, hot offset resistance, un deroffset resistance, storage stability, and fluidity by incorporating a toner resin made of a block copolymer or a graft copolymer obtained by combining a crystalline polyester with a specified amorphous vinyl polymer and paraffin wax. CONSTITUTION:The toner contains the toner resin made of the block copolymer or the graft copolymer obtained by chemically combining the crystalline polyester with the amorphous vinyl polymer having a weight average molecular weight Mw to number average molecular weight Mn ratio Mw/Mn of >=3.5, and the paraffin wax, thus permitting each of low temperature fixability, resistances to hot offset and underoffset, storage stability, and fluidity to be enhanced. |
