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.
