Abstract:
1. An image forming apparatus comprising: an image forming device to form an image of a toner on a recording material; and a fixing device including an endless fixing belt to bear the toner image thereon; a controller configured to control a speed of the fixing device to feed the recording material from 400 to 1,700 mm/sec while heating the recording material to fix the toner image on the recording material, wherein the fixing belt has at least a substrate, a rubber layer located on the substrate and having a thickness of from 400 μm to 700 μm, and a fluorine-containing resin layer located on the rubber layer and having a thickness of from 2 μm to 20 μm, wherein the toner includes: toner particles including: a release agent including at least one of a microcrystalline wax and a synthetic ester wax; and wherein W represents a height of a third falling peak specific to the crystalline polyester resin in a Fourier transform infrared spectroscopy (FT-IR) spectrum obtained by subjecting the toner to FT-IR using a KBr pellet method, and R represents a height of a maximum rising peak specific to the amorphous polyester resin in the FT-IR spectrum.
