Patent ID: 7391149

Claim:
An image forming apparatus comprising: a first substrate having an associated potential-regulated conductive element; a second substrate having, associated therewith, an electrode regulated at a potential higher than that of the conductive element and an anode electrode connected to the electrode via a resistor, all arranged to face the first substrate; a spacer which abuts the conductive element, the electrode and the anode electrode to regulate a distance between the first and second substrates, wherein the spacer includes a base material, and a first resistor film which covers at least a side face of the base material and which is electrically connected to the conductive element, the electrode and the anode electrode; and a second resistor film which covers at least a portion of the spacer facing the resistor, and which is electrically connected to the electrode and the anode electrode, wherein a sheet resistance value of the second resistor film is less than a sheet resistance value of the first resistor film, and a resistance value of the second resistor film between the electrode and the anode electrode is greater than a resistance value of the resistor.
