Claim:
An image forming device comprising: a main casing; a support member mounted in the main casing so as to be pulled out of the main casing in a first direction, the support member supporting a plurality of photosensitive members aligned at intervals along the first direction; a plurality of developing cartridges in one-to-one correspondence with the plurality of photosensitive members, wherein each of the developing cartridges includes a casing and a developing member rotatably supported by the casing, and each is detachably mounted on the support member; a handle provided to the support member on an upstream side of a most upstream side one of the developing cartridges in the first direction; and a pair of interfering parts provided at both ends of the support member with respect to a second direction parallel to a rotational axis of the developing member, wherein: a gap between the pair of interfering parts in the second direction is narrower than a length of the developing member in the second direction; the pair of interfering parts is located between the handle and the most upstream side one of the developing cartridges in the first direction; and each of the interfering parts has a higher height than the handle in a third direction perpendicular to both the first direction and the second direction.
