Abstract: A fixing device includes a fixing belt, a pressuring member, an exciting coil and a belt guide. The pressuring member comes into pressure contact with the fixing belt to form a fixing nip. The exciting coil is provided at an outer diameter side of the fixing belt and configured to generate a magnetic flux to inductively heat the fixing belt. The belt guide supports the fixing belt from an inner diameter side. The belt guide includes a contact part which is in contact with an inner circumferential face of the fixing belt and a non-contact part which is not in contact with the inner circumferential face of the fixing belt. The non-contact part is provided with a slit configured to inhibit induction heating of the non-contact part due to the magnetic flux generated by the exciting coil.

A magnetic flux blocking member configured to block the magnetic flux that passes through the fixing belt is provided between the fixing belt and the non-contact part.

Abstract translation: 定影装置包括定影带，加压构件，励磁线圈和带引导件。 加压构件与定影带压力接触以形成定影辊隙。 励磁线圈设置在定影带的外径侧，并且被配置为产生磁通量以感应加热定影带。 皮带导向器从内径侧支撑定影带。 带引导件包括与定影带的内周面接触的接触部和不与定影带的内周面接触的非接触部。 构造成阻挡通过定影带的磁通的磁通阻挡构件设置在定影带和非接触部之间。
