Abstract:
A charge applying member includes a conductive roller and a shaft. The conductive roller includes a first region in contact with a member to be charged and facing an image forming region of the member to be charged and a second region next to a longitudinal end of the first region and facing a region of the member to be charged outside the image forming region and is configured to apply a charge to the member to be charged. The shaft formed of a metallic material inserted into the conductive roller and configured to be given a voltage from a power supply. A region plated with a metal having a lower ionization tendency than the shaft is formed as a plated region on a surface portion of the shaft corresponding to the first and second regions and a non-plated region is formed on a surface portion of the shaft corresponding to the second region.
