More specifically, the photoreceptor is used in a so-called simultaneous method, in which exposure and development are performed simultaneously to form a 1 ij ji image.

7 has been proposed. In this method, a transparent tetraelectric support t! A photoreceptor having a photoconductive layer formed thereon is used, and the photoreceptor is exposed to light from the transparent conductive support side. During exposure,
The surface of the photoreceptor is rubbed with a magnetic brush made of a conductive magnetic tree to which a bias voltage is applied. At this time, the resistance of the photoconductor between the exposed area and the unexposed area changes, causing a difference in the charge injected into the conductive magnetic triplet that is in contact with the photoreceptor surface, and the difference in the charge fd. The difference in electrostatic adhesion force of the conductive magnetic toner to the surface of the photoconductor (.1) makes development possible.

るのが最適であると考えられている。In this 111-hour method, a seamless belt made of an organic material is used as a transparent conductive support because it is necessary to perform exposure from the transparent conductive support side of the photoreceptor and to downsize the apparatus. , it is considered optimal to install the exposure unit inside the belt.

山からである。However, after extensive study, the inventors discovered that the characteristics required of the photoreceptor used in the simultaneous process are fundamentally different from those of the photoreceptor used in the normal Carlson process. It is the time required for the charge tU body (hereinafter referred to as carrier) generated inside the photoreceptor to move to the surface of the photoreceptor (
This means that the flight time (hereinafter referred to as flight time) must be sufficiently shorter than the exposure time. In the case of the Carlson process, the surface of the photoreceptor is uniformly charged before being exposed to mW light, and then exposed, so the photoreceptor has a so-called half-exposure amount (Es9, or E
While it is sufficient if L/2) is small, in the case of the simultaneous method, there is no normal current process and the time during which voltage is applied to the photoreceptor is the same as that between the conductive magnetic toner and the photoreceptor. limited to the time it is in contact with the surface. Therefore, the carriers generated during the exposure time do not move efficiently to the surface (the change in resistance of the photoreceptor due to exposure is reduced, and as a result, the contrast of development becomes smaller).
It's from the mountain.
前述のフライトタイムについての一つのIn (F、と
なる物性値をして、感光体の移動度があげられる。移動
度が早ければ、フライトタイムは短かくなると汀える。The mobility of the photoreceptor can be raised by taking the above-mentioned physical property value of In (F) for the flight time. If the mobility is fast, the flight time becomes short and stops.
ゆえに、同時法に用いられる感光体に要求される特性の
一項目として、移ff1L:が早いということが掲げら

に長い時間となる。The mobility of the Jμ electric body currently in practical use is approximately 10-'cJ/V*scc, which results in a flight time of 20m5ec, which is much longer than one exposure time.
また、シームレスベルトを使用する限り、可tA性の問
