IMAGE FORMING METHOD AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an image forming method and an image forming apparatus in which neither faulty transfer nor uneven discharge (roughing) occurs. SOLUTION: The image forming method comprises: charging an image bearing member to a predetermined charge potential by a charging means; forming an electrostatic latent image on the charged image bearing member by a latent image forming means; forming a toner image by depositing a toner on the electrostatic latent image by a developing means; transferring the toner image from the image bearing member onto an intermediate transfer member by an intermediate transfer means in a primary transfer section; and transferring the toner image from the intermediate transfer member onto a recording medium by a secondary transfer means, wherein the diameter R (mm) of a secondary transfer roller 13 and the distance A (mm) between a nip center of the secondary transfer roller and a site where paper contacts with a secondary transfer belt at ingress side satisfy the relation of R/402)>Q>15(A2).
