摘要:
A charging apparatus includes a latent image bearing member having a charge generating layer for generating an electric charge by receiving light energy; a light source for emitting light energy for generating the electric charge in the charge generating layer; an electrode; a bias voltage applying portion for applying a bias voltage to the electrode; and an elastic member, which is insulative and transparent, for contacting the electrode to a surface of the latent image bearing member. The electric charge is generated in the charge generating layer by reception of the light energy emitted from the light source, and the surface of the latent image bearing member is electrically charged by applying the bias voltage from the bias voltage applying portion to the electrode. The electrode is provided on the elastic member and is contacted to the surface of the latent image bearing member in a contact area and does not extend to an outside of the contact area.
