Abstract

SG0154 OF THE DISCLOSURE UNIT, PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS A unit includes: a conveying member that conveys developer; a frame that stores the developer and includes a first chamber storing the conveying member, a second chamber, a first opening connecting the first chamber and the second chamber, and through which the developer is passed, and a second opening connecting the interior of the second chamber and the exterior of the frame in an orthogonal direction that is orthogonal to a direction of a rotation axis line of the conveying member; and a filter that allows air to pass the second opening and restricts the developer from passing the second opening, and is fixed to the frame, wherein the frame is displaceable with respect to an apparatus main body in a state where the unit is attached to the apparatus main body, and the filter is displaced with respect to the apparatus main body by the displacement of the frame.
