Abstract
The image forming apparatus includes an image carrier, a developing unit, and a housing. The developing unit includes a toner carrier, a development container, a circuit board, and a board retaining portion. The development container rotatably supports both end portions of a rotating shaft of the toner carrier, and contains developer and the toner carrier. The development container includes a protrusive support portion which protrudes from both end portions of an axial direction and which is pivotably supported by a retaining frame. The development container is pivoted on the protrusive support portion serving as a fulcrum, and the toner carrier is reciprocatively movable so as to come into contact with or separate farther from the image carrier. The board retaining portion is pivotably supported on a fulcrum given by a retention support portion coaxial with the protrusive support portion, and is independent of the reciprocative movement of the development container.
