摘要： Provided are a negatively-chargeable electrophotographic photosensitive member which is free of any increase in residual potential and in which any pinholes due to insulation breakdown do not occur even under two-component development conditions that can satisfy such a high image quality as that required in the market of light printing, and an image forming process and an electrophotographic apparatus which make use of the same. The electrophotographic photosensitive member has, between its cylindrical substrate and photoconductive layer, a first lower-part layer formed of a non-single crystal material containing silicon atoms and a second lower-part layer formed of a non-single crystal material containing silicon atoms, and has, on its photoconductive layer, an upper-part layer formed of a non-single crystal material containing silicon atoms. The first lower-part layer is a layer containing a periodic-table Group 13 element, and the upper-part layer has a region capable of retaining electrification charges.

摘要： PURPOSE:To provide high potential retentivity and to prevent residual potential from being produced by successively forming two amorphous blocking layers each having a specified thickness and contg. a IIIA or VA group atom in the periodic table between a photoconductive layer of amorphous silicon (a-Si) on a support and the support. CONSTITUTION:When an electrophotographic sensitive body having a photoconductive a-Si layer 4 on an electrically conductive support 1 is manufactured, the 1st blocking layer 2 of a-Si having 0.5-2.5mum thickness and the 2nd blocking layer 3 of a-SiO2 having 0.1-9mum thickness are successively formed on the support 1. The layers 2, 3 contain preferably H or halogen, and it is preferable that a small amount of B or P is incorporated to regulate the specific resistance of the layer 2 to OMEGAcm and that of the layer 3 to >=10 OMEGAcm. A protective layer 5 of a-Si contg. O, H, N or C is then formed on the layer 4. Thus, a sensitive body having high potential by electrostatic charge and no residual potential after exposure is obtd. This sensitive body has high resistance to bias for development and a long life.
