Abstract

PURPOSE:To efficiently coat the thick film of a photosensitive paint and to obtain the titled body having uniform film thickness with high productivity by spray-coating a continuously revolving electrically conductive photosensitive substrate in double layers. CONSTITUTION:The scanning started from the point 0 travels successively on outward scanning lines g11, g12, g13... and g1K... and passes through the initial line g11. Then the second scanning is started with g1n+1 as g2n. Namely, the outward scanning on the g11-g1n is finished and the spray coating of a single- layered and uniform film layer by spray scanning is complete. The spray connecting can be conducted with only one outward scanning or return scanning, both scannings can be carried out and double-layered spray coating is performed until a specified thickness is obtained. Consequently, a photosensitive body having an optional film thickness can be obtained by using a paint having the physical property most suitable for the spray scanning and uneven coating due to the dripping of the paint and generation of bubbles can be prevented.

The present invention relates to a method of applying a photoconductor paint, particularly an OPC paint.

(Background of the Invention) Electrophotographic photoreceptors are made by forming a photoconductive layer on a cylindrical drum, flexible endless sheet, or seamless note-like photoreceptor substrate made by various molding methods such as the i7pact method. Alternatively, it is formed by coating various layers depending on the type of electrophotographic process, such as a charge generation layer, a charge transfer layer, and a protective layer. Each of these layers is required to be thin, have a uniform thickness, and be homogeneous in terms of composition and physical properties.

However, with this method, the leading end of the pulling process tends to be a thin film, and it is difficult to freely set the film thickness, so the spray method is attracting attention.

However, in the spraying method using a spray gun, the coating efficiency is low due to the poor adhesion rate of the photoreceptor paint to the rotating or circulating substrate per spray amount. In addition, rapidly drying and floating fine stray particles are caught in the spray airflow and adhere to the substrate surface, forming a granular surface that impairs layer uniformity. The amount of spray is small and the productivity is low.

Furthermore, depending on the composition of the photoreceptor, or when a charge generating material and a charge transporting material are mixed and coated as a single layer, when the film thickness is thick, unevenness and bubbles may occur due to dripping, and the paint concentration may be increased to create a thin film. Although there are methods to avoid this inconvenience by coating, there are limits and it is not possible to deal with the problem satisfactorily.

Furthermore, in the case of e>■, the substrate can be coated with the photoreceptor paint only by one forward scan without using the return scan. However, if e is too large, the applied paint may be blown away by centrifugal force, or the spray particles may become relatively rigid and be blown off as rigid particles, resulting in a decrease in coating quality and coating effect. , since it requires a high-cost coating device, the l is, for example, 1 Qon.
In the case of a cylindrical substrate having a diameter of about 100 rpm, the speed is preferably 600 rpm or less, and more preferably 60 to 300 rpm. (2) will also be determined from a practical standpoint. 12/v is 50
