摘要： A charging apparatus, process cartridge, and image forming apparatus with which current fluctuation values in the charging current can be suppressed, and image defects caused by filming and the like can be prevented, by specifying a permissible gap fluctuation value by quantitatively ascertaining the relationship between the fluctuation value in charging current and the fluctuation value in the gap between the photosensitive body and the charging roller. In a charging apparatus equipped with a charging roller provided at a minute gap away from a photosensitive body, for performing charging, the relationship Gmax−Gmin≦30 (μm) is satisfied when the gap (μm) between the charged side of the photosensitive body and the charging side of the charging roller has a maximum value Gmax (μm) and a minimum value Gmin (μm).
