Title:
定着装置、画像形成装置および熱伝導積層体
Document Type and Number:
Japanese Patent JP7196471
Kind Code:
B2
Abstract:
A fixing device includes a contact portion contacting a recording material transported; a heat source heating the contact portion and including a heat generator extending in a width direction intersecting a transport direction in which the recording material is transported, and a support portion supporting the heat generator, the heat source having a counter surface facing the contact portion, and an opposite surface; a high-thermal-conductivity portion is provided on the opposite surface of the heat source and extends in the width direction such that a part of the high-thermal-conductivity portion overlaps the heat generator of the heat source, the high-thermal-conductivity portion having a higher thermal conductivity than the support portion or the contact portion. A length of an area of overlap between the high-thermal-conductivity portion and the heat generator of the heat source in the transport direction is shorter in a width-direction central portion than in two width-direction end portions.
