摘要： PROBLEM TO BE SOLVED: To provide an excellent color image recording device having an intermediate transfer part structured small and simple being made possible to easily maintain and an intermediate transfer belt unit used for the same. SOLUTION: This intermediate transfer body unit 2 is, arranged opposite to a photoreceptor 11, allowed to house an intermediate transfer body 3 capable of successively transferring respective color image from the photoreceptor 11, and housed in the device main body in a state of being freely attached and detached in the direction orthogonal to the rotary shaft of the photoreceptor 11. The device is made possible to urge an operator to replace the intermediate transfer body 3, before the intermediate transfer body 3 is used to the limit of the life of itself in this intermediate transfer body unit 2.

摘要： PROBLEM TO BE SOLVED: To realize the automatic self temperature control of a heating element itself optimum for fixation and to prevent partial temperature deviation or excessive temperature rising by using a heat generating member made of a magnetic layer and constituting it so that the ratio of its calorific value equal to or above Curie temperature to the calorific value at ordinary temperature when it is excited may be equal to or under a specified value. SOLUTION: In a heating roller 21, magnetic alloy adjusted to obtain the specified Curie temperature is set as base substance and the surface thereof is coated with fluororesin. An induction heating part is constituted by an exciting coil 23 and an alternating power source 24 arranged inside the roller 21. The magnetic alloy of the roller 21 has thickness twice or more as thick as surface depth corresponding to exciting frequency and is constituted so that the calorific value equal to or above the Curie temperature is

摘要： PROBLEM TO BE SOLVED: To provide a color image forming device capable of forming an excellent image and to provide a process unit used for the same by solving a problem caused in a conventional color image forming device that a supply part is not replenished with toner and a supply defect occurs even through the toner remains inside a hopper and a failure occurs in an image due to toner deterioration and toner scattering caused by consecutive use. SOLUTION: In this color image forming device, plural process units (1Bk, 1C, 1M, 1Y) are constituted so that the units respectively store the toner of different colors, are annularly arrayed and integrally rotated and a toner holding chamber is constituted so that the specified amount of the toner is held in the vicinity of a toner supply means to a photoreceptor when the process unit is at an image forming position and the toner is restored inside a developer hopper from the vicinity of the supply means by the gravity of the toner when the process unit is not at the image forming position.

摘要： PROBLEM TO BE SOLVED: To facilitate the assembly and adjustment of a color image forming device by arranging the image forming position and the refuge position, so as to surround an exposure means, and the exposure means inside the loci of the movements of plural image forming units. SOLUTION: A carriage 2 houses four color image forming units 3Y, 3M, 3C and 3BK and is constituted so that the carriage 2 is rotationally supported by a circular tube 21, to rotationally movie photoreceptors 30 for each color between the image forming position 10 and the refuge position except it, in a device main body 1. Then, a laser beam scanner 6 is fixed on a supporting base fixed in the device main body 1 and image signal laser light 8 which is emitted from the laser beam scanner 6 and corresponds to a time sequence two-image signal in the upper part of an image passes through an exposure window provided in the circular tube 21 and further, an optical path 33 formed between the waste toner case 37 of the image forming unit 3Y and a toner hopper 39, to be made incident on the exposed part of the left side surface of the photoreceptor 30 of the image forming unit 3Y in the image forming device 10, so that the exposed part is scanned/exposed in an generatrix direction.
