ADHESION DEVICE AND ELECTROPHOTOGRAPHIC IMAGE FORMING DEVICE

摘要

Provided is an adhesion member which is capable of achieving the amount of heat generation required for an adhesion device with a lower amount of microwave absorbing material, and which can shorten the start-up time (so-called "warm-up time") before the adhesion device reaches a temperature at which adhesion is possible, without compromising characteristics such as flexibility, releasability and durability, functions required in each layer of a heating member. This adhesion device has a heating member, a pressurizing member, and a microwave generating means, and adheres unadhered toner on a recording material by passing the same through the nip formed by the heating member and the pressurizing member, wherein the heating member has a heat-generating layer which generates heat by the microwaves generated by the microwave generating means, and the heat generating layer contains a polymer compound and carbon fibers that have an average fiber diameter of 80-150nm, an average fiber length of 6-10·m, and an absorption peak in the Raman spectrum due to a graphite structure.
