Abstract:
1. An image forming device, comprising: a plurality of photosensitive bodies, one for each color of a composite color image; a plurality of charging units which charge a surface of each of the plurality of photosensitive bodies so that an electrostatic latent image is formable thereon; a plurality of developing units which develop electrostatic latent images formed on the surfaces of the plurality of photosensitive bodies; a plurality of transfer units which transfer developed electrostatic latent images onto a transfer medium; a charging power supply unit which powers the plurality of charging units; a developing power supply unit which powers the plurality of developing units; a transfer supply unit which powers the plurality of transfer units; and a plurality of developing voltage dropping units each of which is disposed between the developing power supply unit and the respective ones of the plurality of developing units and which drop a voltage of a developing power supplied by the developing power supply unit to the plurality of developing units to yield respective developing voltage level gaps in the developing power supplied to each of the plurality of developing units, wherein the plurality of developing voltage dropping units are zener diodes.
