Transfer device

Abstract

Abstract PURPOSE:To obtain an image having enough density, no irregularity and high quality by making the photosensitive surface of an image carrier contact with an intermediate transferring belt at all area where the transferring electric field of a transferring part executing the transferring of the toner image on the image carrier to the intermediate transferring belt is actuated so that the toner image is transferred to the intermediate transferring belt. CONSTITUTION:A tension roller 12 adds tension to the intermediate transferring belt 14 in order to make the intermediate transferring belt 14 turn while the intermediate transferring belt 14 is guided by a contact starting roller 8 and a contact ending roller 10. By the rotation of a photosensitive body 5, the toner image reaches a contact S (an interval between the contacts S and E is an electric field action area, and the contact S is an electric field action starting point) where the transferring electric field starts actions through a transferring roller 6. And the toner image is made to contact with the intermediate transfer ring belt 14 simultaneously as it reaches the contact S, and the toner image is transferred to the intermediate transferring belt 14. Thus, a transferring efficiency is improved, and the image having enough density, no image irregular ity and high quality is obtained on the transferring material.
