ABSTRACT:
A photoelectron emitting member and method of electrically charging fine particles with photoelectrons, wherein the member includes a matrix that is at least composed of a material capable of transmitting ultraviolet rays and a material that is provided on the surface of the matrix or in its neighborhood and which emits photoelectrons upon irradiation with ultraviolet rays or sunlight. The member emitting photoelectrons upon irradiation with ultraviolet rays or sunlight is disposed in an electric field from the side opposite to the irradiated side. The member permits efficient utilization of the energy of ultraviolet rays. When sunlight is applied to the member to have it emit photoelectrons, particles can be electrically charged with energy costs being reduced to substantially zero.
