Abstract: An image forming apparatus includes an image carrier unit, a developing unit, a supporting frame, a retainer and a sheet member. The image carrier unit includes an image carrier on which an electrostatic latent image is formed. The developing unit develops the electrostatic latent image with toner. The supporting frame supports the image carrier unit and the developing unit in an attachable and detachable manner. The retainer is supported by the supporting frame in a turnable manner, and positions the image carrier unit and the developing unit to the supporting frame by being turned upward. The sheet member closes a gap between the supporting frame and the retainer. The sheet member has an upper section supported by the retainer and a lower end section supported by the supporting frame, and at least one of the upper end section and the lower end section is configured to be detachable.

Abstract: A waste toner collecting device includes an intermediate collection box, a conveying path, a conveying screw, an exhaust path and a floating toner collection chamber. The conveying path is provided in the intermediate collection box. The conveying screw is rotatable in the conveying path. Through the exhaust path, air containing a floating toner is sucked and passed. The floating toner collection chamber is provided on a part of the exhaust path in the intermediate collection box. The floating toner collection chamber has a discharge opening opened to an inside of the intermediate collection box and a discharge door. Rotation of the conveying screw in a normal direction turns the discharge door into a storage position where the discharge opening is closed. Rotation of the conveying screw in a reverse direction turns the discharge door into a discharge position where the discharge opening is opened.

Abstract: An image forming apparatus includes an image carrier unit, a developing device, a unit support frame, a retainer, and a developing device moving mechanism. The retainer swings in a first direction, in which the image carrier unit and the developing device are mounted in the unit support frame, to perform positioning of an image carrier, and swings in a second direction, in which the image carrier unit and the developing device are drawn out from a main body of the image forming apparatus, to unlock a positioned state of the image carrier. The developing device moving mechanism associates with the swing of the retainer in the first direction to dispose the developing device at a developing position, and associates with the swing of the retainer in the second direction to dispose the developing device at a separation position.

Abstract: A development device includes a developer carrier, a housing, a layer thickness regulating member and an attachment member. The developer carrier carries a developer developing an electrostatic latent image formed on an image carrier, the developer carrier rotating around an axis. The housing stores the developer carrier and the developer, and has an opening through which the developer carrier is exposed. The layer thickness regulating member is disposed so as to form a gap between the layer thickness regulating member and the developer carrier and regulates a layer thickness of the developer carried on the developer carrier. The attachment member is made of a material has the same thermal expansion property as the layer thickness regulating member. The layer thickness regulating member is fixed to the attachment member using only an adhesive.
