Description

technical field

[0001] The present invention relates to a heating device using far infrared rays. Background technique

[0002] Conventionally, a heating device for heating using far-infrared rays is known. For example, Japanese Unexamined Patent Publication No. 07-159768 (hereinafter abbreviated as "Patent Document 1") discloses such a heating device provided with a mechanism for vertically moving an object to be heated.

[0003] For example, JP-A-11-172026 (hereinafter abbreviated as "Patent Document 2") discloses a heating device that inverts an object to be heated and heats it.

[0004] The heating device can be used to heat, for example, a charging roller (cylindrical shape) of a developing section of an electrophotographic image forming apparatus. Such a charging roller such as figure 1 As shown, in this charging roller 1, a conductive resin layer 3 is formed on the outer periphery of a cylindrical metal core 2, and a surface layer portion 4 is formed on the outer p...
