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 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 image forming apparatus includes an image bearing member, a conductive member, a bias application device, and a control portion. The image bearing member has a photosensitive layer formed on an outer peripheral surface thereof. The conductive member is disposed so as to make contact with an inner peripheral surface of the image bearing member and has a dielectric property. The bias application device applies a bias including an alternating current bias to the conductive member. The control portion controls the bias application device. The image forming apparatus is capable of executing a heating-up mode in which an alternating current bias having a peak-to-peak value twice or more as large as a discharge start voltage between the conductive member and the image bearing member is applied to the conductive member to cause the surface of the image bearing member to be heated up.

Abstract: A cleaning device includes a rotary member, a sheet member, and a toner conveying member. The rotary member is held in contact with a cylindrical surface of an image carrier above a rotation axis of the image carrier. The sheet member is in contact at a distal end thereof with the cylindrical surface of the image carrier above the rotation axis of the image carrier and upstream of a contact position of the rotary member with the cylindrical surface of the image carrier in a direction of rotation of the image carrier. The toner conveying member is disposed above the sheet member and facing the peripheral surface of the rotary member.
