Embodiment 1

[0155] Created using the method shown below image 3 Heat-generating fixing belts of the structure shown, and designated as sample Nos. 101 to 109.

[0156] (Preparation for loop weaving)

[0157] Toray woven fabrics using carbon fibers shown in Table 1 were sewn together with carbon fibers to obtain endless woven fabrics.

[0158] [Table 1]

[0159]

[0160] 1-1 and 1-2 were produced by sewing cloth into a loop. 1-3~1-7 are made of carbon fiber weaving into cylindrical cloth. In Table 1, the thickness represents the equivalent image 3 The thickness of 24a31 in (c).

[0161] The thickness of carbon fiber shows the value measured based on JIS L0101-1978.

[0162] The fiber density of the woven fabric represents a value obtained by visually measuring the number of fibers in a range of 25 mm×25 mm. The thickness of the woven fabric represents a value obtained by measuring a cross-section with a reflection optical microscope.

[0163] (Wrapping of woven fabric with po...

Abstract

Disclosed is a heat-producing fixing belt composed of a heat-producing layer, an elastic layer, and a releasing layer, wherein a pair of electrodes to supply power to the heat-producing layer making contact with the fabric containing carbon fiber are provided on both ends of the cylindrical shape.

Description

technical field [0001] The present invention relates to a heat-generating fixing belt for thermally fixing a dry toner image formed by developing an electrostatic latent image such as electrophotography on an image carrier, and an image forming apparatus using the heat-generating fixing belt. . Background technique [0002] In the past, for image forming apparatuses such as copiers and laser printers, a method of contact heating and fixing an unfixed toner image transferred to an image carrier such as plain paper by using a heat roller method after developing the toner was often used. . [0003] However, in the heat roller system, it takes time to raise the temperature to a temperature capable of fixing, and a large amount of heat energy is required. In recent years, the thermal film fixing method has become the mainstream from the viewpoint of shortening the time (warm-up time) from power-on to copying start and energy saving. [0004] In this fixing device (fixer) of th...
