High voltage switching equipment of developing device for colour image forming apparatus

摘要

A high voltage switching equipment for sequentially supplying a high voltage to color developing devices (10), for developing an electrostatic latent image formed on a photoconductive medium (80) of a color image forming apparatus using color toners includes high voltage applying terminals (12) respectively formed in rear ends of fixed color developing devices (10) contacting the photoconductive medium (80) through a nip, a high voltage applying substrate (16), within which a high voltage circuit is installed, on which connector terminal strips (22) connected to the each high voltage applying terminal are provided on one side, and on which first terminal strips (18) connected to the high voltage circuit and second terminal strips (20) connected to the connector terminal strips (22) are arranged in pairs on the other side with a constant distance, and a high voltage connecting unit (23) connecting the first terminal strips (18) and the second terminal strips (20) arranged on the high voltage applying substrate (16), so that the high voltage is supplied to a relevant developing device.
