Abstract

PURPOSE:To use an a-Si to make a copy possible, by using the a-Si, which has electric resistance increased by irradiation of light and has fatigue effects, for a photosensitive layer to form a copy image. CONSTITUTION:A photosensitive layer L consisting of an a-Si which has electric resistance increased by irradiation of light and has fatigue effects is formed on the outside circumferential face of a conductive drum S consisting of Al or the like to constitute a photoreceptor 1. While rotating the photoreceptor 1, the exposure of an original image is performed with an energy higher than a degree, where the electric resistance of the photosensitive layer L is increased and remains as fatigue, by an exposure mechanism 2. Electrostatic charge is given to the photosensitive layer L by a corona charger 3. Electric charge is held only in parts, where the electric resistance is increased to form an electrostatic charged image. This electrostatic charged image is inverted and developed with a toner by a developing equipment 4. The toner image is transferred to transfer paper or the like. When the photosensitive layer L is heated by a heater 8 and is irradiated with infrared rays of an infrared-ray lamp 9, it is recovered from fatigue. Thus, the a-Si is used to perform the copy.

Currently, electrophotography is widely used to obtain copies of original images. This is done by using a photoconductive photoreceptor, charging the surface of the photosensitive layer, and then performing image exposure, and taking advantage of the fact that the photosensitive layer has low resistance in the areas irradiated with light. An electrostatic charge image is formed by eliminating the electrostatic property of the image, and this is developed with toner.
A'* is a method of transferring this toner image onto a transfer material to form a copy image.

On the other hand, recently, amorphous silicon (hereinafter referred to as "a-silicon") has been used because it does not have such problems and can advantageously form a thin layer over a large area with relative ease. Research is being carried out to obtain electrophotographic photoreceptors, but since the photoconductive photosensitive layer made of a-silicon basically has a low dark resistance, it has a fatal drawback of low charge retention ability. Although various means have been proposed to solve this problem, they are still insufficient, and it is difficult to apply them to the ordinary electrophotographic process as described above.

In the present invention, as shown in FIG. 1, on the outer peripheral surface of a conductive drum S made of metal such as aluminum,
A photoreceptor 1 is formed by forming a photoreceptor layer made of &-silicon, which has a fatigue effect that increases its electrical resistance when irradiated with light.
As shown in FIG.
A conductive drum S is grounded and rotated in the direction of the arrow, and includes a side light mechanism 2 that irradiates a light image from a document onto its outer peripheral area, a corona belt m unit 8, a developer 4, and a transfer discharger 5. are arranged in this order in the rotational direction of the photoreceptor 1, and further provided with a transfer discharger 5, a static elimination discharger 6, a toner cleaner 7, a heater 8, and an infrared lamp 9 in this order. A copy image is formed using the following method.

That is, while rotating the photoreceptor 1, the exposure mechanism 2 first generates an amount of energy greater than 60!, which increases the electrical resistance of the photosensitive layer and causes it to remain as fatigue. EIW・
The original image is exposed to white light of sec/cj or more. The phenomenon in which a fatigue effect related to electrical resistance occurs in a-silicon due to irradiation with light is known as the Stabler-Wronski effect, and this effect is large in a-silicon.
-Silicon can be formed, for example, by a method as explained in the experimental example below. This exposure increases the electrical resistance of the photosensitive layer in the portion irradiated with light, that is, the portion corresponding to the non-image portion of the original image, and as a result, an image is formed based on a so-called resistance value distribution.

Next, a corona charger 8 applies an electrostatic charge to the exposed photosensitive layer. The Wpt load may be positive or negative. Through this charging process, charge is retained in the areas where the electrical resistance has increased, but the charges imparted to the areas corresponding to the image areas that are not irradiated with light damage the photosensitive layer and the conductive drum S. The electrostatic charge image disappears by escaping through the photosensitive layer or by being injected with an opposite charge from the conductive drum S through the photosensitive layer, and as a result, an electrostatic charge image having a negative relationship with respect to the original image is formed.

As a specific means for transferring, an electrostatic transfer method using a transfer discharger 6 as in the illustrated example can be used, and then a copy image of the original is obtained by fixing.

The resistance distribution of the photosensitive layer in this state is still maintained as it is, and therefore, by charging again with the corona charger 8, the same electrostatic charge image as in the process described above is formed.

On the other hand, when the heater 8 is energized to heat the photosensitive layer and subsequently irradiated with infrared rays from the infrared lamp 9, the fatigue in the photosensitive layer is recovered and the increased resistance value disappears. As a result, the photosensitive layer returns to its original state, and the next copy #I#! Used to form I. The infrared light to be irradiated here preferably has a wavelength in the near-infrared region. In order to recover from this fatigue, it is necessary to perform infrared irradiation while the photosensitive layer is heated, and the heating temperature T is approximately 200 to 300°C. By recovering from this fatigue, it is possible to continuously form images based on new documents.

On line I), the resistance value decreases by infrared irradiation to the value r8 at temperature T of the unexposed portion (ljl), and is restored to the initial value rO along line (2) by cooling to room temperature.
