1. An image forming apparatus comprising:
an electric potential controller to fix a surface electric potential on a photosensitive surface of a photosensitive member to a prescribed value;
a power source to supply prescribed voltage or current to the photosensitive surface through a transferring surface of an intermediate transferring member; and
a resistance detector to detect a current value flowing through the intermediate transferring member against the prescribed voltage supplied from the power source or a voltage value generated in the intermediate transferring member against the prescribed current, and detect a resistance value of the intermediate transferring member based on the detected current value or voltage value.
