Problems solved by technology

Then, the driving of the transparent resin layer forming apparatus including the photosensitive drum 100 after the fixing belt becomes unstable, and the transparent resin layer cannot be uniformly formed, which is another problem.
[0015] In order to overcome the above problems, it is necessary to reduce the fixing pressure and speed, and to perform drive control with high performance, which in turn causes other problems such as enlarged equipment and reduced productivity

Embodiment 1

[0128] figure 2 is a view showing the structure of a clear coat forming apparatus provided with a particle layer forming apparatus 12 (thermoplastic particle layer forming apparatus) according to Embodiment 1 of the present invention.

[0129] As the particle layer forming device 12, a thermoplastic particle layer forming device is selected, which includes a photosensitive drum 18, a charging device 19 opposite to the photosensitive drum 18, an exposure device 20, and a device for developing a thermoplastic particle layer. A particle layer developing device 21, and a transfer roller 22 for transferring from the photosensitive drum 18 to the fixing belt 11. As the granular layer developing device 21, a non-contact type one-component developing unit is used. The particle layer developing device 21 negatively charges a particle layer by sandwiching it between a semiconductor developing roller and a silicone rubber blade. AC and DC bias voltages overlapping each other are appli...

Embodiment 2

[0138] Embodiment 2 is described below, and the description of the same components as in Embodiment 1 is omitted.

[0139] In Example 2, in the same manner as in Example 1, when no granular layer is formed, the granular layer forming device 12 shrinks from the fixing belt 11, and when the end of the recording sheet 9 passes through the fixing between the heating roller 23 and the pressure roller 24 The particle layer forming device 12 and the fixing belt 11 contract with each other at the nip portion.

[0140] Figure 5 Among them, (e) represents a change in the running speed of the fixing belt 11, indicating that the speed in the upper direction is accelerated and the speed in the lower direction is decelerated. When the recording sheet 9 enters the fixing nip portion between the heating roller 23 and the pressure roller 24 , the running speed of the fixing belt 11 is reduced, causing the heating roller 23 and the pressure roller 24 to rotate on the recording sheet 9 . When...

Embodiment 3

[0143] Embodiment 3 is described below, and the description of the same components as in Embodiment 1 is omitted.

[0144] In Embodiment 3, there is provided a switching selection mechanism for selecting the driving means for the granular layer forming device or the thermal fixing device by switching at least while the particle layer forming device is forming the particle layer on the fixing belt.

[0145] In Embodiment 3, when the driving means of the granular layer forming device or the thermal fixing device is selected by switching, the granular layer forming device and the thermal fixing device are driven by the same driving means. In this case, as the same driving device for driving the particle layer forming apparatus and the thermal fixing device, a thermal fixing device driving device is used.

[0146] Also, in Embodiment 3, when the thermal fixing device driving device is used as the same driving device that drives the particle layer forming device and the thermal fix...

Abstract

A transparent coat layer forming apparatus of the present invention includes: a heat-fixing device provided with a fixing belt; a particle layer forming apparatus for forming a particle layer made of transparent toner on the fixing belt of the heat-fixing device; plural rollers including a transfer roller for stretching a transfer region of the fixing belt to which the particle layer is transferred from the particle layer forming apparatus in a plane shape; and a retract mechanism for retracting the fixing belt stretched inaplane shapeby the plural rollers including the transfer roller from the particle layer forming apparatus, wherein the particle layer is formed on the fixing belt by the particle layer forming apparatus, and the particle layer formed on the fixing belt of the heat-fixing device is overlapped with a transfer material with an image transferred thereto in a fixing nip portion, followed by heating and pressurizing, whereby a transparent coat layer made of the particle layer is formed on the transfer material with the image transferred thereto.

Description

technical field [0001] The present invention relates to a clear coat forming apparatus for forming a clear toner layer on the surface of a color image formed by a copier or printer using an electrophotographic system, an electrostatic recording system, etc., or by an image forming apparatus such as a facsimile machine A clear coat, and a color imaging device using the clear coat to form a device. Background technique [0002] Generally, in the case of forming a color image on a transfer material of a copier or printer employing an electrophotographic system, an electrostatic recording system, etc., or an image forming apparatus such as a facsimile, a color original is copied in the following manner, for example. In the image forming apparatus, a color original is set on a color scanner, the color original is irradiated with light, and the light reflected from the color original is separated into three colors (such as RGB) by the color scanner and read. Image data of a color...
