<p>An image forming apparatus has an image bearing member (1), a contact member (3) contacting with the image bearing member (1), detecting means for detecting the voltage-current characteristic between the image bearing member and the contact member, and counting means for counting the frequency of image formation. Image forming conditions on the image bearing member are controlled on the basis of the detected result by the detecting means and the counted value of the counting means.</p> |
