Filed: 1993-11-16
Abstract: PURPOSE:To markedly reduce a load for driving a conveying belt, generated due to electrostatic attractive force, by forming a fine irregular shape over a contact surface total unit in. at least any one of the contact surfaces with the conveying belt of an electrostatic attractive force generating means or with the electrostatic attractive force generating means of the conveying belt. CONSTITUTION:A fine irregular shape 30 is formed over a total unit in the upper surface of an electrode protecting member 14D brought into contact with a conveying belt 9. In this way, since the electrostatically attracted conveying belt 9 and a belt static charger 14 are brought into contact through the fine irregular shape 30, a contact area between the conveying belt 9 and the belt static charger 14 is decreased remarkably small as compared with in the case of contact with the fellow flat smooth surfaces. Since the conveying belt 9 and the belt static charger 14 are electrostatically attracted through a fine air layer of the fine irregular shape 30, both the belt and the charger are not in close adherence such as in the case of contact with the fellow flat smooth surfaces. Accordingly, even when the conveying belt 9 is electrostatically attracted to the belt static charger 14, a load of driving the conveying belt 9 is not increased.
