By rotating the photoreceptor of the system (hereinafter referred to as the Se-As photoreceptor), an electrostatic latent image is formed on the photoreceptor while its surface is moved cyclically in the direction of the radial direction. An electrophotographic copying process in which a latent image is developed and the resulting visible image is transferred onto a recording medium such as paper is well known.

It was not surprising that the separation performance of the recording medium from the photoreceptor after transfer was also significantly improved.

It is difficult to imagine whether this pre-transfer exposure may cause damage to the light on the 5e-As photoreceptor.

Rotation of photoconductor 1, charging of photoconductor 1f by charger 2, image exposure of photoconductor 1 by light image of original document Timing of pre-transfer exposure by PTL 4? When the electrophotographic copying process was repeated 10 times in succession with the settings as shown in Figure 2, the surface potential of the photoreceptor measured by the electrometer 10 was as follows: In the area corresponding to the image area, the change was as shown in curve 3-1 in Figure 3, and in the non-image area, the change was as shown in curve 3-2 in the same figure. Subject::\1 1iii1 The image density of the second and subsequent copies of the 1 image visibly decreases, and even in the first copy, it is exposed to light by PTL 4 before being charged by charger 2. The image density of the area corresponding to the body part was much lower than the image density of the area other than the wrinkles.
また、シ枚目以後の画像にはいわゆる残像が見られた。In addition, so-called afterimages were observed in the images after the second one.

分布として作用し。This 5-sum phenomenon is caused by optical fatigue of the photoreceptor 1 due to PTL 4. That is, the long wavelength component of the light from the tungsten lamp used as the PTL 4 penetrates the photoconductive layer of the photoreceptor 1 and generates carriers deep inside the pigeon. Among the generated carriers, electrons with low mobility are trapped and act as a space charge distribution within the photoconductive layer.

の増大と抵抗の低下とをもたらす。Due to this influence, the charge level of the photoreceptor after exposure by PTL 4 decreases. That is, P.T.L.
Exposure according to 4 causes the photoconductive layer of photoreceptor l to increase its capacitance and decrease its resistance.

Of course, one song 13-3 has a potential at a portion corresponding to an image portion.One song IkI3-4 has a potential at a portion corresponding to a non-image portion.

Almost no decrease in image density was observed.

) Carrier generation is mostly limited to the surface.
このため、光導電1曽における静電容量は、殆ど増加せ
す、従って、感光体の光疲労が生じないためである。For this reason, the capacitance in the photoconductor 1 is almost increased, and therefore, optical fatigue of the photoreceptor does not occur.

The peripheral surface of the photoreceptor from the 4σ) position clockwise up to the charger 2 does not receive the path light from the PTL 4.

The image and opening degree of the portion corresponding to the area subsequent to the writing area were lower than the image of 6 degrees of the portion corresponding to the peripheral surface area where there is no writing area. The problem is that in the part illuminated by PTL 4,
Even if the light has a short wavelength, there are many photoelectrons, so the number of generated carriers is also large, and it is thought that this is because the medium receiving resistance near the surface of the photoconductive layer is temporarily lowered.
そこで次に、チャージャー2による帯電のタイミングと

The timing shown in Figures 1 and 4 satisfies the 2σ] Kasou in Hoka: 4/J.

Miyato: Since the purpose is to perform light beaming on the photoreceptor before transfer with a low amount of light, for example, it is possible to use a tungsten lamp as a PTL and cut off unnecessary light components with a filter to perform path light before transfer. However, if you do it like this, in reality,
The cost of filters is quite high. Contrary to this, when the light source exits the light source, there is no public security that uses a filter,
It is possible to realize a light source for pre-transfer light in one song.

The photoreceptor is uniformly charged while being moved cyclically to the photoreceptor, and then imagewise exposed with light that cuts out light of 650 nm or more to form an electrostatic latent image. , a visible image could not be obtained on the photoreceptor? 17 tit
In an electrophotographic copying method for transferring onto a recording medium. The light source for pre-transfer light includes electroluminescence, a light emitting diode, and a fluorescent wrap, which contain light with a wavelength width of 480 to 580 nm at least 70% of the energy in the visible light range. 1' When starting the copying process, the photoreceptor is rotated, and the light source for pressure is emitted before the transfer, and the peripheral surface area of the photoreceptor is uniformly exposed to σ] light from this light source. An electrophotographic copying method characterized by forming an electrostatic latent image within the image.
