To prevent a belt and image forming means from being stained by spilled toner and also to reduce the vibration of an exposure means (6) and to facilitate maintenance. An image forming apparatus is of a tandem type in which mage forming stations Y, M, C, K for respective colors are arranged along a transfer belt (14). Each image forming station Y, M, C, K has an image carrier (17), a charging means (19) and a developing means (20) which are arranged around the image carrier (17). The image forming apparatus forms a multi-color image by passing the transfer belt (14) through the respective image forming stations. The transfer belt (14) is laid around a driving roller (12) and a driven roller (13) with a constant tension. In one embodiment either one of the driving roller and the driven roller is positioned obliquely above the respective other roller such that the belt tension side at the time of driving the transfer belt is on the lower side, and the image carriers of the respective image forming stations are in contact with the belt tension side. In another embodiment both the transfer belt and image forming apparatus are located above the exposure means. Still other embodiments show one or two pivotally movable frame sections containing the transfer blade. <IMAGE>
