Image Forming Apparatus, Conductive Member Service Life Determination Method, And Conductive Member Service Life Determination Program

A conductive member service life determination method executed in an image forming apparatus provided with a conductive member to form an image on a sheet using a toner, the conductive member service life determination method comprising:

• a voltage acquisition step of acquiring a biased voltage value as a voltage value obtained by applying a bias to the conductive member;
• an environment acquisition step of acquiring an environment condition measurement value representing an internal environment condition;
• a step of transforming the biased voltage value acquired in the voltage acquisition step into a virtual voltage value indicated by the conductive member as the biased voltage value under the standard environment condition in which the environment condition has a predetermined standard condition on the basis of the environment condition measurement value acquired in the environment acquisition step;
• and
• a step of determining a service life of the conductive member on the basis of the virtual voltage value.
