Abstract
A transfer roller cleaning mechanism is brought into contact with a transfer roller so as to remove a harmful substance contained in a developer remaining on the transfer roller after a transfer step. Upon completion of printing of a predetermined number of pages, a fixation roller is moved apart from the transfer roller and a developed image for cleaning is formed over the entire printing area on a photosensitive body . This developed image is made into a film shape, which is transferred onto the transfer roller . The film-shaped developed image for cleaning is cleaned by the transfer roller cleaning mechanism
