Provided is an image forming apparatus in which a filming property to a photoreceptor is improved in a high-speed output system, low-temperature fixing is possible, toner storage property and fixing high-temperature wrapping property are good, and fixing strength with a fixing paper is high. . Furthermore, it is possible to provide an image forming apparatus that can achieve a high developer life while maintaining a highly reliable image, reduce deterioration fog in a low temperature and low humidity environment, and print a high quality image. In an image forming apparatus including a fixing device that fixes a visible image on a recording medium by heat and pressure, a system speed is 400 to 3000 mm / sec, and a pressing surface pressure of the fixing medium of the fixing device is a 5N / cm 2 ~90N / cm 2 , and toner used in the visible image formation, a toner containing at least an amorphous polyester resin and a crystalline polyester resin and a colorant and a release agent, and crystal Forming apparatus in which the ratio of the crystalline component of the conductive polyester resin in the toner is 0.10 to 20%.
