Patent ID: 8592118

Claim:
A toner, comprising: a first binder resin, including: an amorphous polyester resin (a) having a polyhydroxycarboxylic acid skeleton in its main chain, the polyhydroxycarboxylic acid skeleton comprising optically-active monomers having an optical purity X of 80% by mole or less, the optical purity X being represented by the following formula: X (% by mole)=| X ( L -form)− X ( D -form)| wherein X(L-form) and X(D-form) represent ratios (% by mole) of L-form and D-form optically-active monomers, respectively; a release agent, including: an ester of a fatty acid having an average carbon number of 18 to 24 with glycerin or a polyglycerin having an average polymerization degree of 2 to 10, the ester having a melting point of 55 to 80° C.; a release agent dispersing resin, wherein the release agent dispersing resin includes a polyester resin comprising a fatty acid ester having a branched structure comprising a fatty acid having a carbon number of 16 to 24 and a polyol having 3 or more valences; and a colorant.
