Two temperature areas are set at a higher temperature side and at a lower temperature side of target temperature respectively. The power stage of the temperature areas at the higher temperature side is set to −1 and the power stage of the temperature areas at the lower temperature side is set to +1. Thus, a current value is varied little and generation of flicker can be reduced. Further, A temperature can be always converged into the target temperature. When a temperature is in a temperature area near to the target temperature, the power stage is maintained except for a case in which a temperature has passed through a temperature area other than this near temperature area and the target temperature area and enters this near temperature area for the first time. Thus, an amplitude of power can be suppressed.
A fusing device for use with an image forming device, which supplies toner to a latent image that is obtained by being exposed to light on a charged image carrier to form the latent image into an image and transfers a resultant toner image from the image carrier to a recording material, and for fixing the toner image on the recording material by applying a predetermined quantity of heat to the recording material,
A heat generating devices comprising:
A temperature control method for controlling a temperature of a heat generating member by making the heat generating member generate heat in a plurality of power stages,
