Abstract:
An image forming apparatus includes a fixing unit including a fixing belt, a pressurizing rotator that forms a nip portion between the fixing belt and the pressurizing rotator by pressurizing an outer peripheral surface of the fixing belt, a first heating rotator that is provided so as to contact an inner peripheral surface of the fixing belt in the nip portion and heats the fixing belt, and a second heating unit that heats the fixing belt separately from the first heating rotator, wherein a toner to be used has physical properties described in the specification and includes an amorphous resin, a crystalline resin, and paraffin wax having a melting temperature of 60° C. to 80° C., and an absolute value of a difference in a melting temperature between the crystalline resin and the paraffin wax is 10° C. or less.

Claim (Index 1):
An image forming apparatus comprising:\n an image holding member; a charging unit configured to charge a surface of the image holding member; an electrostatic charge image forming unit configured to form an electrostatic charge image on a charged surface of the image holding member; a developing unit that includes an electrostatic charge image developer containing an electrostatic charge image developing toner, the developing unit being configured to develop the electrostatic charge image on the surface of the image holding member to thereby form a toner image; a transfer unit configured to transfer the toner image to a recording medium; and a fixing unit configured to fix the toner image on the recording medium, wherein the fixing unit includes:\n a fixing belt, \n a pressurizing rotator that forms a nip portion between the fixing belt and the pressurizing rotator by pressurizing an outer peripheral surface of the fixing belt, \n a first heating rotator that is provided so as to contact an inner peripheral surface of the fixing belt in the nip portion, the first heating rotator being configured to heat the fixing belt, and \n a second heating unit that is provided on at least one of an inner peripheral surface side and an outer peripheral surface side of the fixing belt, the second heating unit being configured to heat the fixing belt separately from the first heating rotator, and \n wherein the electrostatic charge image developing toner includes:\n a binder resin containing an amorphous resin and a crystalline resin; and \n paraffin wax, \n wherein the toner has a volume average particle diameter of 6 \u03bcm to 9 \u03bcm, a shape factor SF1 of 140 or more, and a toluene-insoluble portion of greater than 30% by weight and not greater than 35% by weight; the paraffin wax has a melting temperature of 60\u00b0 C. to 80\u00b0 C.; and an absolute value of a difference between a melting temperature of the crystalline resin and a melting temperature of the paraffin wax is 10\u00b0 C. or less.
