摘要： A frame for an image forming apparatus including at least one functional unit includes a front member (1), a rear member (5), a base member (4), and a pair of elevated supporters (2,3). The front (1) and rear (5) members at least support the functional unit. The base member (4) supports at least the rear member (5). The pair of elevated supporters (2,3), fixed at least to the base member (4), have a U-shaped form in its cross-section. The elevated supporters (2,3) are spaced a given distance apart and disposed facing an open part of the U-shaped form of the pair of elevated supporters (2,3). The elevated supporters (2,3) supports both lateral rim portions of the front member (1) at a given position of the pair of elevated supporters (2,3). The front member (1) is indirectly fixed with the base member (4) via the elevated supporters (2,3), and positions the functional unit at a given position.

摘要： At an end portion of a middle frame (605), a first protrusion (571) and a second protrusion (572) are arranged protruding parallel to each other. A plate-like arm (573) extends from a leading end of the second protrusion (572) in a direction towards a leading end of the first protrusion (571). A control protrusion (575) is integrally formed at a leading end of the plate-like arm (573). On the other hand, a rear side frame (602) has a recessed portion (581). When the first protrusion (571), the second protrusion (572), and the plate-like arm (573) are inserted into the recessed portion (581), the control protrusion (575) passes a latching protrusion (585) provided to the recessed portion (581), and the control protrusion (575) and the latching protrusion (585) are latched by facing each other.
