Abstract:
A charging device is provided. A charging device includes a charging section and a discharge product adsorption removal section. The charging section includes a shield case having a shield opening, a discharge electrode, and a rotation shaft which is parallel to a rotation axis of a photoreceptor. The discharge product adsorption removal section has an adsorption layer that adsorbs a discharge product and is disposed downward in a vertical direction of the photoreceptor. The charging section is displaceable about an axial line of the rotation shaft from a position where the shield opening opposes to the photoreceptor to a position where the shield opening opposes to the discharge product adsorption removal section.
