VOLTAGE SUPPLY DEVICE FOR DEVELOPING DEVICE, AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a voltage supply device for a developing device in which a high voltage contact is switched with the developing device fixed in order to suppress a deterioration in picture quality and the shortening of the life of a photoreceptor due to contact shock caused when the developing devices are replaced and to improve the switching reliability of the high voltage contact.

SOLUTION: The voltage supply device for supplying voltage to developing devices by colors comprises a connection circuit board (195) connected to a high voltage supply source for generating high voltage; a plurality of fixed contact terminals each of which is formed on one end of a developing device of each color; and a voltage switching unit (110) for selectively connecting the connection circuit board (195) and the fixed contact terminal in order to selectively supply voltage from the high voltage supply source to the developing device of each color.
