摘要： PURPOSE:To improve reproducibility of electrophotographic characteristics, sensitivity to He-Ne laser beams, and heat resistance and to extend a life by making the alloy element concn. of the Te-contg. layer of an Se type photosensitive body almost constant in the film thickness direction. CONSTITUTION:The alloy element concn. of the Te-contg. layer (Te-Se alloy layer) 4 of an Se type photosensitive body formed on a conductive substrate 1 is made almost constant in the film thickness direction. The Se photosensitive body is obtained by laminating an Se layer 3 and the layer 4 successively on the substrate 1. The layer 4 is formed by vapor deposition at a temp. about 100 deg.C higher than that of the liquid phase line of the binary constitutional diagram. The layer 4 thus formed makes the content of Te constant in the film thickness direction, enhances glass transition point and heat resistance, and extends its life, and further, eliminates scattering of electrophotographic characteristics, and enhances reproducibility. Since the Te content has correlation with, e.g. sensitivity to He-Ne laser beams, the sensitivity can be held at the optimum value by controlling the Te content.
摘要翻译：目的：提高电子照相特性的再现性，对He-Ne激光束的敏感性和耐热性，并延长使用合金元素的寿命。的Te-contg。 Se型感光体层在膜厚度方向上几乎恒定。构成：合金元素浓度的Te-contg。形成在导电基板1上的Se型感光体的层（Te-Se合金层）4在膜厚度方向上几乎恒定。 Se感光体通过在基板1上依次层叠Se层3和层4而获得。层4通过在温度下气相沉积形成。比二元结构图的液相线高约100℃。由此形成的层4使Te的含量在膜厚方向上保持恒定，提高玻璃化转变点和耐热性，延长寿命，进一步消除电子照相特性的散射，提高再现性。由于Te含量与对He-Ne激光束的灵敏度，可以通过控制Te含量将灵敏度保持在最佳值。

摘要： PURPOSE: To obtain an electrophotographic receptor superior in printing resistance and long term durability, by vaccum evaporation of an amorphous selenium or an selenium alloy on a substrate consisting of an age-hardening type aluminum alloy and cooling them at a specified cooling rate.
CONSTITUTION: An age-hardening type aluminum alloy having ≥60Hv Vickers hardness is used as a substrate, and an amorphous selenium or a selenium alloy is made vaccum evaporation on the substrate as a photosensitive layer. The photosensitive layer consisting of the amorphous selenium or the selenium alloy and having ≥5H surface hardness by the pencil hardness test method is formed by cooling this substrate and the photosensitive layer at ≥5°C/min on the age-hardening type aluminum alloy substrate having ≥60Hv Vickers hardness to obtain the desired photoreceptor. As said age-hardening type aluminum alloy, an Al-Mg-Si type is preferable. The cooling rate of 5W20°C/min is obtained by compulsorily cooling both the substrate and the photosensitive layer after the vacuum evaporation.
