Abstract
An image forming apparatus includes means for supplying a developing agent between electrically independent recording electrodes and a recording medium which is movable relative to the recording electrodes while a signal voltage is applied to the recording electrodes so as to form images. In order to prevent electric charges from being induced in the recording medium due to the electric charges accumulated in the vicinity of the recording medium, and thereby prevent unnecessary toner from being attached to the recording medium, the surface of a resin member which opposes the recording medium fulfills a charging preventing function.
