1. An image forming apparatus including a photosensitive member, a charger configured to charge the photosensitive member, an exposing unit configured to expose the photosensitive member, a developing member configured to supply developer to the photosensitive member, an image forming unit that includes a detecting member configured to flow current between the detecting member and the photosensitive member, a controller configured to control operations of the image forming unit, and a casing, and the image forming apparatus configured to be able to identify the photosensitive member,
wherein the controller performs operations comprising:
controlling the exposing unit to expose a first ratio to a full scan width of the photosensitive member and thus to form a first exposed section, and to expose a second ratio smaller than the first ratio thus to form a second exposed section,controlling the detecting member to acquire:a first voltage in a case where a first test current flows in the first exposed section;a second voltage in a case where the first test current flows in the second exposed section;a third voltage in a case where a second test current larger than the first test current flows in the first exposed section; anda fourth voltage in a case where the second test current flows in the second exposed section; andidentifying the photosensitive member based on the first to fourth voltages. |
