    摘要： An image forming apparatus includes an image holding member, a charging unit; an electrostatic image forming unit, a development unit, a transfer unit; a fixing unit, and a cleaning unit. A toner for electrostatic image development contains a binder resin containing an amorphous resin and a crystalline resin, and paraffin wax. The toner has a volume-average particle diameter of 6 μm to 9 μm, a shape factor SF1 of 140 or more, and a toluene insoluble content within a range of 25% to 40%. The melting temperature of the paraffin wax is 60° C. or more and 80° C. or less. The absolute value of difference between the melting temperature of the crystalline resin and the melting temperature of the paraffin is 10° C. or less.
