<p>A toner suitable for developing an electrostatic latent image is described comprising (a) a polyester resin of a non-linear copolymer having, as a side chain, an aliphatic hydrocarbon group containing 3 to 22 carbon atoms, said copolymer being obtainable by polymerization of an etherified bisphenol, a dicarboxylic acid, and either a polyhydric alcohol with 3 or more OH groups or a polycarboxylic acid containing 3 or more carboxylic acid groups, or both, (b) at least one alkylene-bis-aliphatic acid amide compound represented by the general formula:
<CHEM>
wherein R1 and R2 are independently saturated or unsaturated aliphatic hydrocarbon groups having not less than 10 carbon atoms, R3 and R4 are independently a hydrogen atom and a group represented by - OCR5 wherein R5 is a saturated or unsaturated hydrocarbon group and n is a positive integer and (c) a wax containing not less than 20% by weight of ester component, the needle penetration degree of the wax being not more than 4.</p> |
