Abstract:
An image forming apparatus includes an image holding member, a charging unit, an electrostatic charge image forming unit, a developing unit, a transfer unit, a fixing unit including a fixing belt, a pressurizing rotator that forms a nip by pressurizing an outer peripheral surface of the fixing belt, a sliding member that slides on an inner peripheral surface of the fixing belt in the nip, and a pressing member that presses the fixing belt in the direction of the pressurizing rotator, wherein a toner to be used includes a binder resin containing an amorphous resin and a crystalline resin and has specific physical properties described in the specification, and paraffin wax having a melting temperature of 60° C. to 80° C., and an absolute value of a difference between the melting temperature of the crystalline resin and the melting temperature of 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, and the developing unit being configured to develop the electrostatic charge image on the surface of the image holding member to 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 onto the recording medium, wherein the fixing unit includes: a fixing belt; a pressurizing rotator configured to form a nip by pressurizing an outer peripheral surface of the fixing belt; a sliding member configured to slide on an inner peripheral surface of the fixing belt in the nip in a contact manner, and a pressing member configured to press the fixing belt in the direction of the pressurizing rotator, and wherein the electrostatic charge image developing toner includes: a binder resin containing an amorphous resin and a crystalline resin; and paraffin wax, wherein the toner has a volume average particle diameter of 6 ilm to 9 ilm, 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.
