    Abstract: A developer container includes a container main body having an internal space and a developer discharge port; a movable wall moving in the internal space toward the developer discharge port; a detection surface which is a part of an inner peripheral surface that divides a storage space of a developer in the container main body and which becomes a detection region of a first detection sensor which detects the developer in the storage space; and a rotating body arranged in the storage space and capable of rotating around a rotary shaft along the first direction. The rotating body is mounted with a cleaning member which cleans the detection surface, a stirring member which stirs a developer in the storage space, and a detection target member to be a detection target of a second detection sensor which detects presence of the container main body.

    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: An optical scanning device includes a light emitter, a scanner, a first detector and a determiner. The light emitter outputs a beam. The scanner scans within a given area determined in advance with the beam output from the light emitter. The first detector is arranged on an optical path of the beam in the given area and detects the light quantity of the beam. The determiner determines light quantity shortage of the light beam if the light quantity detected by the first detector is below a first threshold set in advance and above a second threshold indicating a light quantity smaller than the first threshold and determines an abnormality in a scanning operation by the scanner or an abnormality of the light emitter if the light quantity detected by the first detector is below the second threshold.
