Abstract
An image fixing apparatus having a linear heating body with an endless belt entrained around thereon, using an electrical power supply to provide pulsating power to the linear heating body. Additionally, a pressure body interposes the subject to be fixed containing an image on the endless belt, and the image is heated by the linear heating body through the endless belt. The subject is thereafter cooled and removed from the endless belt. The image is formed by using a toner containing a binder which contains a resin as a main component. Either the softening point or the melting point of the toner is between 50° C. to 160° C., and the viscosity of the toner is between 10 to 1013 centi-poise at a temperature greater than either the softening point or the melting point of the toner.
