Patent ID: 8369747

Claim:
A charging device comprising: a charging section for charging a surface of a photoreceptor which is provided to be rotatable about a rotation axis; and a discharge product adsorption removal section provided on a downward side in a vertical direction of the photoreceptor and having an adsorption layer composed of an adsorbent that adsorbs a discharge product generated in charging the surface of the photoreceptor by the charging section, the charging section including: a shield case having a longitudinal axis parallel to the rotation axis of the photoreceptor and having a shield opening which faces and opens in one direction perpendicular to the longitudinal axis, a discharge electrode provided in the shield case in parallel with the longitudinal axis, and a rotation shaft to which the shield case is fixed and which is disposed to be rotatable about an axial line parallel to the longitudinal axis, and the rotation shaft being rotatable 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.
