发明名称 ELECTROPHOTOGRAPHIC TONER
摘要 PROBLEM TO BE SOLVED: To obtain an electrophotographic toner which is excellent in low temperature fixability and heat resistant preservability and excellent in glossiness of printed matter.SOLUTION: There is provided an electrophotographic toner including particles in which aggregated particles obtained by aggregating an aqueous dispersion of a polyester resin for toner are fused, wherein resin particles dispersed in the aqueous dispersion have a volume median particle diameter (D) of 0.07 to 0.50 μm, the weight ratio between resin particles (precipitation component) which is precipitated and resin particles (non-precipitation component) which is not precipitated when the aqueous dispersant is centrifuged under specific centrifugation conditions is 55/45 to 97/3 as a precipitation component/a non-precipitation component, and the non-precipitation component has a volume median particle diameter (D) of 0.01 to 0.05 μm.
