る。Organic photoconductive materials have advantages over inorganic photoconductive materials, such as low cost, high productivity, and non-polluting properties, but have the disadvantage of low sensitivity. For this reason, several sensitization methods have been proposed, but it is known that an effective method is to use a functionally separated photoreceptor in which a charge generation layer and a charge transport layer are laminated.

、これらの点についても十分に考慮する必要がある。When selecting a binder resin for the charge generation layer, consider the dispersibility of the charge generation substance, the stability of the dispersion, the adhesion to the conductive layer or subbing layer, and the resistance to organic solvents contained in the charge transport layer. It is necessary to take into account the properties of the paint, such as solubility and penetration resistance. Furthermore, depending on the type of binder used, the electrophotographic properties of the electrophotographic photoreceptor, such as sensitivity, potential retention, or photohistory properties, must be taken into account. Since the durability characteristics such as storage stability, durability against environmental changes, and durability upon repeated use vary, it is necessary to fully consider these points.

ニルブチラール樹脂の化学式は次のようになる。When the resin was selected with the above points in mind, it was found that polyvinyl butyral resin or fatty acid cellulose ester resin is most suitable for the charge generation layer. The chemical formula of polyvinyl butyral resin is as follows.

。The respective ratios are that the cetyl group is 5 molar or less, the butyral group is 60 to 81 molar, and the hydroxyl group is the remainder. Examples of the cleaved fatty acid cellulose ester resin include cellulose acetate, cellulose propionate, cellulose butyrate, cellulose valerate, cellulose caffroate, cellulose enanthate, cellulose caprylate, cellulose caprate, cellulose laurate, cellulose myristate, and palmitate. Examples include resins made from triesters such as cellulose or mixed esters such as cellulose acetate propionate and cellulose acetate butyrate.

合体等が挙げられる。The charge transport layer provided on the charge generation layer contains a polycyclic aromatic compound such as anthracene, pyrene, phenanthrene, coronene, etc., or indole, carbazole, oxazole, inoxazole, thiazole, imidazole, pyrazole, oxadiazole, etc. in the main chain or side chain. It is formed by dissolving a charge-transporting substance such as a compound having a nitrogen-containing cyclic compound such as azole, pyrazoline, thiadiazole, or triazole, or a hydrazone compound in a resin that has film-forming properties. This is because the charge transporting substance generally has a low molecular weight and has poor film-forming properties by itself. Examples of such resins include polyester, polysulfone, polycarbonate, polymethacrylic acid esters, polystyrene, styrene-acrylonitrile copolymer, styrene-methyl methacrylate copolymer, and the like.

The application process is shown in the attached drawing. In this case, the substrate 1, which is closed on one side, is immersed in the coating liquid 2,
Next, the substrate is pulled up at a constant speed to form a coating.

This is what we sought.

It contributes to acceptance potential, sensitivity, optical memory effect, durability, environmental characteristic fluctuations, etc., and its optimal value is determined depending on the type of pigment and binder resin used. Usually 0.03~
The coating thickness is selected to be about 0.5 μm, but there is a certain relationship between the concentration of the coating liquid and the coating speed in order to coat the film to this specified thickness. The higher the concentration and coating speed, the thicker the film.
Then, it was found that the relationship of TccC8 is 6-. That is, in order to obtain a predetermined film thickness, the coating speed may be increased when the concentration of the coating liquid is low, and the coating speed may be slowed when the concentration is high.

て電子写真感光体として不適当である。However, as a result of the inventor's experiments, when polyvinyl butyral resin or fatty acid cellulose ester resin is used as a binder, when the non-volatile content concentration is lower than 0.3%, the pulling application speed is increased by 40 crnZ. The desired film thickness cannot be obtained unless it is pulled at a high speed, and if it is pulled up at such a high speed, the coating layer will sag, that is, the coated surface will rub off due to gravity, making the film thickness uneven. It is unsuitable as an electrophotographic photoreceptor.

Furthermore, if the nonvolatile content concentration is greater than 3 yen, the film thickness will become too thick no matter how slow the pulling speed is, and the fluidity of the paint will decrease, making it unsuitable.

This allows for stable coating.
