Abstract: An image forming apparatus includes a developer container having a movable wall therein, a determination unit, a movable wall driving unit, and a movable wall driving controller. The determination unit outputs first determination information when a number of outputs of a signal indicating that a detection sensor has detected a developer is less than a threshold value, and outputs second determination information when the number of outputs thereof is equal to or greater than the threshold value. The movable wall driving unit includes a first driving motor for moving the movable wall and a first driving circuit for controlling driving thereof. The movable wall driving controller includes a signal controller. The signal controller transmits a drive permission signal for the first driving motor when the first determination information is output, and transmits a drive non-permission signal for the first driving motor when the second determination information is output.

Abstract: A developing device includes a housing containing a developer, a developer carrier, a developer conveying path, a developer conveying member, and a plurality of paddle members. The developer conveying path includes a first conveying path and a second conveying path. The developer conveying member is disposed in the second conveying path and includes a rotating shaft and spiral blades formed around the rotating shaft. The developer conveying member is rotationally driven to convey the developer in the second direction and feeds the developer to the developer carrier. The plurality of paddle members project in a radial direction from the rotating shaft of the developer conveying member at one circumferential position on the rotating shaft. The plurality of paddle members is contiguously arranged in the axial direction of the rotating shaft to connect the spiral blades adjacent to each other in the axial direction.

Abstract: A development device includes a development housing, a development roller, a supply roller and a layer thickness regulating member. The development housing stores a nonmagnetic one-component toner. The development roller is formed by a cylindrical elastic body, and moves in a same direction as a rotational direction of a rotatable photosensitive drum at a development nip area while coming into contact with the photosensitive drum. The supply roller is formed by a cylindrical elastic body, and supplies the toner to the development roller and collects the toner from the development roller. The development roller has a surface free energy within a range of 5 mJ/m2 or more and 27 mJ/m2 or less.

Abstract: An image forming apparatus includes a housing in which a developing device is disposed, a cover member attached to the housing, a developer storage container to be detachably attached to the developing device, and a sensor unit. The developer storage container includes a container body having a storage space for storing a developer and a developer discharge port, and a moving wall configured to move in the container body. The sensor unit is arranged at a detection position where a detection sensor faces a specific area located above the developer discharge port on an outer peripheral surface of the container body when the cover member is in a closing posture, and arranged at a detection disable position where the detection sensor is distant from the specific area when the cover member is in an opening posture.

Abstract: A developing device of the present disclosure includes a developing roller, a toner supply roller, a regulation blade, a casing, a toner receiving support member, a toner receiving member, a vibration generation unit, and a vibration inhibition member. The toner receiving support member is disposed in the casing so as to be opposed to the developing roller or the toner supply roller in an area between the regulation blade and an image carrier. The toner receiving member has a toner receiving surface that receives toner dropping from the developing roller, and is supported so as to be swingable about an end edge thereof on a toner supply roller side as a fulcrum. In a state where the toner receiving member is not vibrating, the vibration inhibition member is in contact with each of both end portions of the toner receiving surface in a longitudinal direction thereof.
