Image forming apparatus having intermediate transfer member with residual surface potential characteristic

摘要

An image-forming apparatus, equipped with an intermediate transfer member 3 having a surface layer that holds a toner image primary-transferred from a latent image-supporting member temporarily on the surface layer and allows secondary transfer of the toner image held thereon to an image receiving medium,wherein, when the moving distance of the intermediate transfer member surface from the secondary transfer region 15 to the first primary-transfer region 16 is designated as L (mm) and the moving speed of the intermediate transfer member as S (mm/second), the residual surface potential of the intermediate transfer member L/S seconds after application of the secondary transfer voltage is 1/20 or less of the first primary transfer voltage V1.
