ABSTRACT:
An electrophotographic developer composition for flash fusing containing at least a binder resin based on a polyester resin and a colorant, the polyester resin being formed between an acid component, not less than 80 mol % of the acid component being phthalic acid series dicarboxylic acid and an alcohol component, not less than 80 mol % of the alcohol component being bisphenol A alkylene oxide adduct, the polyester resin having an acid value of not more than 10.0 KOH mg/g, a softening temperature of not less than 95.0.degree. C. and not more than 125.0.degree. C. as determined using a flow tester of the "koka-shiki" type and a glass transition temperature of not less than 50.0.degree. C. and not more than 80.0.degree. C. as determined by DSC, whereby substantially no odor is produced upon flash fusing.
