PROBLEM TO BE SOLVED: To provide electrophotographic toner which has both of excellent low-temperature fixability and electrostatic charge stability. SOLUTION: The electrophotographic toner contains a low softening point polyester resin having a softening point of 80 to 120°C and a high softening point polyester resin of a softening point of >120°C and≤160°C. The viscosity at 160°C of the low softening point polyester resin is 500 to 10,000 Pa s, and the ratio of the viscosity at 140°C to the viscosity at 180°C is≤10. The weight ratio of the low softening point polyester resin to the high softening point polyester resin is 20/80 to 90/10. COPYRIGHT: (C)2005,JPO&NCIPI
