In addition, conventional image forming methods include a step of charging the surface of the photoconductive layer, irradiating the surface of the photoconductive layer with focused light such as a laser beam while modulating the intensity, or further scanning the surface of the photoconductive layer to charge the light irradiated area. It included a step of erasing the image and forming an electrostatic latent image.

An electrostatic latent image had to be formed using a laser beam or the like for each print. In this case, there is a limit to the intensity of the laser beam, and there is also a limit to the intensity modulation speed, making it extremely difficult to quickly output multiple sheets of the same original. In addition, Xerox has proposed an image forming method using xerolithography technology for processing a large number of sheets, but this method requires maintenance because the photoreceptor is disposable and has the disadvantage of increasing running costs. .

The purpose is to provide a method.

The image forming method of the present invention includes a step of forming an image on the thermochromic layer of the photoreceptor of the present invention by heat, a step of uniformly charging the surface of the thermochromic layer, and a step of uniformly exposing the formed image side to form an electrostatic latent image. The electrostatic latent image is visualized using charged particles.

It is possible to perform development and quickly output multiple copies of the same original. Furthermore, since the thermochromic layer can be made reversible, the photoreceptor can be reused any number of times.

電荷移動層4の二1からなる機能分離型を採っている。[Example 1] Figure 1 shows the structure of the photoreceptor of the present invention. The thermochromic layer No. 1 is shown in the 4th Non-Impact Printing Technology Papers, p. 57-60, and is made by dispersing organic low-molecular substance particles of about 1 μm in resin, and has a thickness of 1 μm.
A resin protective film is formed on the surface with a thickness of about 0 to 20 μm. The thermochromic layer 1 together with the resin protective film provides electrical insulation properties. A photoconductive layer N2 is formed under the thermochromic layer 1. The photoconductive layer may be an organic photoconductor or an inorganic photoconductor, but in this example it is an organic photoconductor. The organic photoconductor is of a functionally separated type consisting of a charge generation layer 3 and a charge transfer layer 4.

The charge transfer layer is a film made by dissolving hydrazone-based, stilbene-based, benzidine-based, or other materials in a resin. The thickness of the photoconductive layer is 1
It is about 0-50 μm. The photoconductive layer 2 has a charge generation layer formed thereon, which is the opposite of the conventional structure.

This is the configuration to take. The thermochromic layer, charge generation layer, and charge transfer layer are all formed by sequentially coating and drying.

の出力が可能である。In the case of the photoreceptor having this configuration, the thermochromic layer can reversibly take on a transparent state and an opaque state, and a visible image can be obtained by using heat application means such as a thermal head on the thermochromic layer. This point will be explained using FIG. Assume that the initial state at room temperature is completely opaque. Next, when the temperature is raised to T2 by heating with a thermal head or the like, it becomes transparent, and even if the temperature is then returned to room temperature, the transparent state is maintained and a visible image can be obtained. By heating the entire Thermocomic layer to T3 and then returning it to room temperature, the entire surface becomes opaque and can be returned to its initial state. This cycle can be repeated and the thermochromic layer can be shaped many times. By using this visible image as an exposure mask, it is possible to perform pattern exposure on the photoconductor any number of times by exposing the entire surface of the photoconductor to light from the thermochromic layer side. Therefore, once an image is written, the photoreceptor stores the image and can easily output multiple sheets of the same image.

The thermal head 6 is brought into contact with the thermochromic layer in this state, and the thermal head 6 is energized to generate heat according to the image desired to be formed, and by this heat, a transparent portion 7 is partially formed on the thermochromic layer and an image is written (see Fig. 3).

の推移を第4図に示す。In this example, it is negatively charged. Since the thermochromic layer 1 is insulating, the thermochromic layer alone can hold charges. At this time, since there is no barrier to prevent charge movement at the interface between the photoconductive layer and the conductive substrate, holes are injected into the photoconductive layer, and furthermore, the charge transfer layer in this example is of the hole transfer type. The injected holes move within the charge transfer layer and reach the interface with the thermochromic layer (FIG. 3(B)). The prisons that reach the interface are captured by traps in the charge transfer layer and are fixed near the interface, making them unable to move. Next, the thermochromic layer is irradiated with ions of opposite polarity (in this example, positive) to the charge charged on the thermochromic layer in the previous step (Figure 3 (C)).
). Further, in this state, when the photoconductor is irradiated with uniform light 10 from the thermochromic layer side, the photoconductor is exposed in a pattern. In other words, conductive charges are generated in the charge generation layer of the photoconductor corresponding to the area heated by the thermal head, changing the charge distribution inside the photoconductor layer, resulting in a potential distribution corresponding to the image formed on the thermocomic layer. is formed on the surface of the photoreceptor (FIG. 3(D)). In this case, the exposure is uniform over the entire surface, and there is no need to form a beam or the like, and a sufficient amount of light can be secured using a low-output light source, and an extremely short exposure time is sufficient. Next, the obtained electrostatic latent image is developed with positive toner 11 to make it visible (FIG. 3(E)). After that, the recording paper 12 is brought into contact with the photoconductor, and positive ions are irradiated from the back side of the recording paper by the corotron 13, to transfer the toner on the photoconductor to the recording paper (Fig. 3 (E)), and a fixing process is performed to form an image. Finish forming. The latter part of image formation from development to fixing is the same as the conventional electrophotographic process. When outputting multiple sheets, return to step (B) and repeat the process. When the required number of sheets have been output, the entire thermochromic counterfeit is heated to T3 to return the entire surface to opaque, and the entire thermochromic layer is further irradiated with AC corona to erase the electric charge and prepare for the next image formation. FIG. 4 shows the change in potential on the surface of the photoreceptor from steps (B) to (D).

In this example, the photoreceptor 13 has a dome shape, and various units are arranged around the drum, and images are formed while rotating in the direction of an arrow 15. The writing device 16 is a line-type thermal head, which has no moving parts and is highly reliable and compact6.The initialization heater 25 uses an infrared lamp heater. Infrared lamp heaters have a fast response and high controllability, so they do not overheat the photoreceptor. Other units are those used in conventional electrophotographic process image forming apparatuses.
