FIXING MEMBER AND FIXING UNIT - A simplified explanation of the abstract

• This abstract for appeared for patent application number 18190498 Titled 'FIXING MEMBER AND FIXING UNIT'

Simplified Explanation

The abstract describes a fixing member that has a tubular shape and is capable of generating heat. The fixing member includes a conductive layer that is divided into segments, which are arranged in a row along the length of the tubular shape and are electrically isolated from each other. Each segment covers the entire circumference of the tubular shape. The conductive layer is designed in such a way that the heat generated at the ends of the fixing member is less than the heat generated at the center when an alternating magnetic field is applied to the entire length of the fixing member, and the temperatures at the center and ends are equal.

Original Abstract Submitted

A fixing member includes a conductive layer that generates heat when a circulation current in a circumferential direction of the fixing member having a tubular shape is induced. The conductive layer includes segments arranged in a row in a longitudinal direction of the tubular shape and electrically separated from each other. Each segment is formed continuously over an entire circumference of the tubular shape in the circumferential direction. The conductive layer is configured such that a heat generation amount in an end portion of the fixing member in the longitudinal direction is less than a heat generation amount in a central portion of the fixing member in the longitudinal direction when an alternating magnetic field is applied to a whole area of the fixing member in the longitudinal direction in a state where a temperature of the central portion is equal to a temperature of the end portion.
