摘要： A method for manufacturing an electrophotographic photosensitive member using plasma CVD includes steps of placing a cylindrical base member in a reactor which can be evacuated, the reactor having an electrode therein, so as to be spaced apart from the electrode, introducing a raw material gas for deposited film formation into the reactor, and applying an alternating voltage of a rectangular wave having a frequency in the range of 3 kHz to 300 kHz between the electrode and the cylindrical base member so that a potential at one of the electrode and the cylindrical base member with respect to a potential at the other becomes alternately positive and negative, to decompose the raw material gas, and forming a deposited film on the cylindrical base member. The magnitude of the potential difference between the electrode and the cylindrical base member is selectively controlled.

摘要： An electrophotographic photosensitive member production process is provided having the steps of placing a cylindrical substrate having a conductive surface in a first film-forming chamber, and decomposing a source gas with high-frequency power to deposit on the cylindrical substrate a first layer formed of a non-single-crystal material, taking out of the first film-forming chamber the cylindrical substrate with the first layer deposited thereon, and placing the cylindrical substrate with the first layer deposited thereon in a second film-forming chamber, and decomposing a source gas with a high-frequency power to deposit on the first layer a second layer having an upper-part blocking layer formed of a non-single-crystal material. Even where abnormal growth portions called spherical protuberances are present on the photosensitive member surface, they can be made not to appear on images, and image defects can vastly be remedied.
