PROBLEM TO BE SOLVED: To provide an image forming device that embodies reduction in imbalance of applied pressure to first and second developer conveyance bodies.SOLUTION: A developing device 20 comprises: a receptor 21; a support body 29 that supports the receptor 21 fixed to a main body housing F movably in a direction where the receptor is contacted to and separated from a developed body; first and second developer conveyance bodies (22 and 24) that are arranged such that peripheral surfaces face the developed body; a pair of first spring members (201 and 202) that presses the receptor 21 toward a developed body 11 at one end in a rotation axis direction of the first and second developer conveyance bodies, and is located at residual apexes of a first triangle H1 surrounding gravity G of a part excluding the support body 29 of the developing device 20 with a rotation axis O of the developed body as one apex when projected in a rotation axis direction of the developed body; and a pair of second spring members (203 and 204) that presses the receptor 21 at the other end in the rotation axis direction thereof, and is located at the residual apexes of a second triangle H1 surrounding the gravity G. |
