ELECTROPHOTOGRAHIC SENSITIVE BODY

摘要

PURPOSE:To obtain a good output image which is free from ground staining and does not show a density decrease even when the titled photosensitive body is used in inferior environment of a low temp. or high humidity by providing heat sources into grooves formed on the inside peripheral surface of a base body. CONSTITUTION:Four grooves 3-6 are formed at equal intervals on the inside peripheral surface of the cylindrical aluminum base body 2 in the stage of drawing the base body to manufacture said body. A photoconductive layer 7 is formed by vacuum deposition of an arsenic-selenium alloy on the outside peripheral surface of the body 2 to constitute the photosensitive body 1. The film-like heat sources 8 consisting of resistance wire-contg. polycarbonate are thereafter inserted into the respective four grooves, by which the photosensitive body contg. the heat sources are formed. The mounting of the heat sources to the photosensitive body is made easy by providing such grooves and since the heat sources are surely contained in the photosensitive body by contacting with the inside peripheral surface of the base body, the thermal conductivity efficiency in the heating stage considerably improved. The grooves have the advantage to improve the cooling efficiency by conversely acting as radiation fins in the stage of cooling and further contribute to the reduction of the weight of the photosensitive body.
