摘要

An image forming apparatus includes an apparatus main body and an intermediate transfer unit including an intermediate transfer belt, the intermediate transfer unit being provided as being attachable to and removable from the apparatus main body by sliding movement in a first direction. The apparatus main body includes a main body-side guide portion for guiding the intermediate transfer unit along the first direction. The intermediate transfer unit includes a side frame including a frame portion extending like a frame with the first direction being defined as a longitudinal direction thereof, the side frame being provided adjacently to the intermediate transfer belt in a second direction orthogonal to the first direction, and a unit-side guide portion to be engaged with the main body-side guide portion. The unit-side guide portion is provided not to protrude outward relative to the frame portion in the second direction.
