摘要： An electrostatic latent image forming apparatus includes a dielectric drum (10) a surface of which is uniformly charged in a predetermined polarity by a charging corotron (16). A recording head (18) includes a transparent base plate (30), a transparent electrode (32) and a photoconductive layer (34) composed of an amorphous silicon are formed on the transparent base plate in this order. A plurality of discharging electrodes (36) are formed on the photoconductive layer. A bias voltage (46) having a reverse polarity of the charged polarity being charging by the charging corotron is applied. When a light signal in accordance with an image to be formed is entered on the back surface of the transparent base plate, carriers, that is, holes and electrons are generated in the photoconductive layer, the carrier having the same polarity as the bias voltage is discharged onto the dielectric drum through the discharging electrodes. Electric charges are removed or reduced at a portion on the dielectric drum where such discharge occurs, and therefore an electrostatic latent image in accordance with the light signal being entered is formed on the dielectric drum.
