1. A developing device comprising:
a developing chamber provided with a developing agent-holding body rotatable around a first rotation axis extending in a first direction and configured to hold a developing agent, and a supplying roller rotatable around a second rotation axis extending in the first direction and configured to supply the developing agent to the developing agent-holding body; a first developing agent-accommodating chamber configured to accommodate the developing agent and arranged at a position below the developing chamber; a first rotating member disposed in the first developing agent-accommodating chamber, comprising a first shaft extending in the first direction and a first wing connected to the first shaft and elastically deformable, and configured to rotate so that the first wing slidably contacts with an inner surface of the first developing agent-accommodating chamber; a second developing agent-accommodating chamber which is arranged adjacent to the developing chamber and adjacent to an upper portion of the first developing agent-accommodating chamber, and to which the developing agent in the first developing agent-accommodating chamber is supplied by rotation of the first rotating member; and a second rotating member disposed in the second developing agent-accommodating chamber, comprising a second shaft extending in the first direction and a second wing connected to the second shaft and elastically deformable, and configured to rotate so that the second wing slidably contacts with an inner surface of the second developing agent-accommodating chamber and to transport the developing agent in the second developing agent-accommodating chamber toward the developing chamber; wherein the first rotating member is disposed so that a virtual vertical surface including the second rotation axis of the supplying roller intersects a rotation trajectory of the first wing of the first rotating member; wherein the second rotating member is disposed so that the second shaft of the second rotating member is positioned above the first shaft of the first rotating member and below the second rotation axis of the supplying roller in a vertical direction; and wherein the second rotating member is disposed so that the second shaft of the second rotating member is positioned on a side opposite to the first rotation axis of the developing agent-holding body with respect to the virtual vertical surface including the second rotation axis of the supplying roller. |
