<p>PROBLEM TO BE SOLVED: To provide an image forming method for obtaining many sheets with images of good quality with hardly causing toner contamination on a contact type electrifying roller. SOLUTION: As for the image forming method for electrifying a photoreceptor by a contact type electrifying roller to which a bias is applied, forming an electrostatic image on the electrified photoreceptor, developing the electrostatic image with toner constituted of at least binding resin and coloring agent, transferring the toner image to a transfer material, and then heating and fixing the toner on the transfer material, the surface resistance of the contact type electrifying roller is controlled to 20 to 160 MΩand the quantity of monomer left in the toner is controlled to be <=300 ppm in the image forming device.</p> |
