Abstract

PURPOSE:To obtain a photosensitive layer having a barrier layer which is hard to produce a trouble about picture quality by coating a metallic substrate, with a solution of org. titanium compd. followed by calcining it in an oxidative atmosphere, thereby forming a layer composed of titanium oxide on the substrate, and subsequently, laminating a photosensitive layer on the obtd. layer. CONSTITUTION:At the time of producing the titled body, the org. titanium compd. is dissolved in a suitable solvent so as to control viscosity of the obtd. solution to that suitable for coating it, followed by coating the obtd. solution on the metallic substrate. The obtd. substrate is sufficiently dried to remove the solvent, followed by heat-treating the obtd. substrate at a prescribed temp. in the oxidative atmosphere, thereby forming a layer composed of titanium oxide having <=5mu thickness on the metallic substrate. And then, the photosensitive layer is laminated on the obtd. layer. Thus, the stable electric characteristic of the titled body is obtd, even in a changing surrounding. At the time of laminating the photosensitive layer on an upper layer of the titled layer, the titled body having the barrier layer which is hard to produce the trouble about the picture quality is obtd.

[Prior Art] In general, Carlson type electrophotographic photoreceptors require stability of dark area potential and bright area potential in order to form an image with constant image density and no background smudge when charging and exposure are changed to green. It has become important.

For this reason, it has been proposed to provide a layer that functions as a barrier layer between the photosensitive layer and the conductive layer. The layer functioning as such a barrier layer is also required to have good adhesion to the conductive layer and the photosensitive layer.

Until now, it has been known to use resins such as polyurethane, polyamide, polyvinyl alcohol, epoxy resin, casein, methylcellulose, phenolic resin, and nitrocellulose as a layer provided between the photosensitive layer and the conductive layer. When a photoreceptor using this layer is used with a green color, the bright area potential increases and the dark area potential fluctuates.Especially in a low humidity environment, when the photoreceptor is used with a green edge, the bright area potential increases and the dark area potential changes. This method has the disadvantage that it is not possible to produce copies with constant image quality under changing environments. Therefore, in order to eliminate these drawbacks, we created a film by applying a coating in which powders such as TiO2, ZnO, and carbon black were dispersed in polymer paints such as phenol resin, epoxy resin, and acrylic resin. A single-layer barrier with excellent potential stability was proposed, with little change in electrical properties such as resistance and capacitance even in harsh environments. However, even with the above barrier layer, problems such as environmental fluctuations in electrical properties mainly due to the resin used as a binder and deterioration of image quality due to paint dispersibility, coating properties, etc. tend to occur.
