摘要： An image forming apparatus is provided with a photosensitive drum in which a toner image is formed on surface thereof; an intermediate transfer belt to which the toner image of the photosensitive drum is transferred via a primary transfer portion and the transferred toner image is transferred via a secondary transfer portion to a paper; and a wrap-out roller which abuts against a rear surface of this intermediate transfer belt so as to apply tension to the intermediate transfer belt. This wrap-out roller forms the primary transfer portion which causes the intermediate transfer belt to abut against the photosensitive drum in a wrap shape, and forms a flat plane portion toward the secondary transfer portion. This wrap-out roller is arranged within a projection area which is directed from a secondary transfer roller toward the photosensitive drum.

摘要： An image forming apparatus includes an image carrier which has a predetermined center of rotation and on which a toner image is formed, a developing device which has a developing roll that rotates while carrying a toner on the surface thereof and that conveys the toner to a developing position, an intermediate transfer member which is disposed in an approximately flat shape and circulatingly moves, and a fixing unit which fixes the toner image on the transfer material thereon at a predetermined fixing position. In the image forming apparatus arranged as described above, both the image carrier and the developing roll are disposed in a triangle region formed by the approximately flat-shaped intermediate transfer member, a vertical line in contact with the intermediate transfer member, and a horizontal line in contact with the intermediate transfer member, thereby the size of the image forming apparatus can be more reduced.
