PURPOSE:To enhance low temperature fixability, hot offset resistance, un deroffset resistance, fluidity, and durability by incorporating a specified polyester and 2 kinds of specified waxes. CONSTITUTION:The toner contains the polyester having a chloroform insoluble fraction in an amount of >=5wt.% and the paraffin wax and one of alkylene- bis-(fatty acid carboxamide) waxes represented by formula I in which each of R1 and R2 is an optionally saturated and >=10C aliphatic hydrocarbon group, optionally same or different from each other; each of R3 and R4 is H or -OCR5, optionally same or different from each other; R5 is optionally saturated aliphatic hydrocarbon group; and n is a positive integer, thus permitting each of low temperature fixability, resistances to hot offset and underoffset, fluidity, and durability to be enhanced. |
