FIXING DEVICE AND IMAGE FORMING APPARATUS

摘要

A fixing device includes a roller, an endless belt, and a heat generating member disposed in a space inside the endless belt, extending in a width direction of the endless belt, and pressing the endless belt against the roller. A sheet is passed through a nip formed between the roller and a portion of the endless belt pressed by the heat generating member, such that an image on the sheet is fixed thereto. The heat generating member includes first and second heat generating portions that are adjacent to each other along the width direction and independently operable from each other. A boundary of the first and second heat generating portions extends in a direction inclined with respect to a sheet conveying direction.

主权项

1. A fixing device, comprising:
a roller; an endless belt having a portion facing the roller; and a heat generating member disposed such that the portion of the endless belt is between the heat generating member and the roller, the heat generating member extending in a width direction of the endless belt and pressing the portion of the endless belt against the roller such that a sheet can be passed in a sheet conveying direction through a nip formed between the roller and the portion of the endless belt and an image on the sheet can be fixed thereto, wherein the heat generating member includes a first heat generating portion and a second heat generating portion that are separated from each other along the width direction, and each of the first and second heat generating portions are independently operable, and a boundary between the first and second heat generating portions including at least a portion extending in a direction that crosses the sheet conveying direction.
