PROBLEM TO BE SOLVED: To solve the problem in which: when a fixing device includes divided magnetic cores divided into two or more, it is difficult in manufacture to have the distances between the divided cores completely equal to each other, and if the plurality of distances between the divided cores varies and are made unequal to each other due to the manufacturing tolerance, uneven heating (hereinafter referred to as right and left uneven heating) may occur, in which a heat generation distribution in the axial direction of a heating rotating body is different between right and left. ! SOLUTION: A magnetic core is divided into two bodies of equal length, and the division position is brought to coincide with the center position of a fixing sleeve. ! COPYRIGHT: (C)2015,JPO&INPIT |
