Abstract
A recording medium carrier system of an image forming apparatus is constituted by independent units as a paper supply cassette, a paper feed unit, a transfer unit, a fixing unit, and a paper ejecting unit. An intermediate transfer unit in the transfer unit is provided with an intermediate transfer belt to which a toner image formed on a photoconductive drum is primarily transferred at a primary transfer position and which secondarily transfers the toner image on a recording medium at a secondary transfer position, and a driving roller for circulating the intermediate transfer belt. The primary transfer position is arranged close to the driving roller.
