A developer supplying device includes an inflow path; a guide path having an inlet to which a lower end of the inflow path is connected, the guide path extending diagonally downward from the inlet, the guide path guiding the developer to a developing unit; and a transport unit disposed in the guide path, the transport unit including a helical screw blade and a holder that holds the helical screw blade, the transport unit transporting the developer to the developing unit by rotating. In at least a part of a region in the guide path facing the inlet, a pitch of the helical screw blade in a horizontal direction is greater than or equal to a width of the inlet, and the holder is located at a position displaced from the rotation axis of the transport unit. |
