Document Type and Number:
Japanese Patent JP7433956
Kind Code:
B2
Abstract:
An image forming apparatus includes an image forming portion, a fixing portion, and a control portion. The fixing portion forms a nip portion to nip a recording material and includes heat-generating elements along a direction orthogonal to a conveying direction of the recording material. The fixing portion fixes the image on the recording material using heat. The image forming apparatus changes a control target temperature for each heating area heated by each of the heat-generating elements in accordance with the image to be formed on the recording material. When forming the image after a jam clearing process in which the recording material nipped in the nip portion is removed, the control portion changes a distribution of a control target temperature of the whole heater in the direction in which the heat-generating elements are aligned to a second distribution different from a first distribution corresponding to the image.
