Abstract:
Disclosed is an image forming apparatus including a toner feed unit used in a developing device and provided near a top surface of a body casing. The toner feed unit includes a frame that includes a toner container storage space portion including a curved concave portion formed of a material different from a material constituting the body casing, and has supporting surfaces, in a part of a top surface of the space, that support side portions of a device mounted on the body casing and a rear portion of the device connected to the side portions by surface contact. The frame has legs that extend from a position, which is located opposite to the device to be mounted, toward an installation surface of the body casing. The frame is built in the body casing.
