Abstract: An image forming apparatus includes an apparatus main body and a plurality of sets each including a photosensitive member and a transfer member. The plurality of sets is disposed in a linear arrangement in the apparatus main body. The photosensitive member and the transfer member of each set sequentially interpose a transfer medium therebetween, thereby sequentially transferring a developer image borne on each photosensitive member onto the transfer medium. A contact distance is defined for each set. The contact distance is a distance from a contact start position at which the photosensitive member starts contacting the transfer medium to a contact end position at which the photosensitive member separates from the transfer medium. The contact distance is greatest for the set farthest downstream in a conveying direction for conveying the transfer medium.
