Abstract
An image forming apparatus includes an image bearing member, a contact member contacting with the image bearing member, a detector for detecting the voltage-current characteristic between the image bearing member and the contact member, and a counter 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 detector and the counted value of the counter.
