<P>PROBLEM TO BE SOLVED: To provide toner that contains high amount of rosin derived from biomass, and has excellent hot-offset resistance, charge stability, and cohesion resistance, as well as a method of manufacturing the toner. <P>SOLUTION: Toner contains at least a binder resin, colorant, and a mold release agent. The binder resin contains a polyester resin A obtained by subjecting an aromatic dicarboxylic acid, rosin, and polyalcohol to polycondensation; and a cross-linked resin C obtained by subjecting the polyester resin A and an epoxy resin B having a plurality of glycidyl groups to crosslinking reaction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
