Abstract
Electrostatic latent image forming device includes a first insulating base plate, a plurality of first electrodes and a plurality of second electrodes disposed to form a matrix with a second insulating base plate interposed therebetween. Each of the second electrodes has a space area where a creeping corona discharge is caused to occur by applying a voltage between the first and second electrodes. The second insulating base plate is supported by the first insulating base plate. In the electrostatic latent image forming device, through holes are formed in the first insulating base plate, and conductors in conduction to the first and second electrodes are filled into the through holes. Connecting parts in conduction to the conductors are provided on the back surface of the first insulating base plate to apply voltages to the first and second electrodes through the conductors.
