Abstract: A cleaning device includes a cleaning blade member that has a tip abutting a surface of an image carrier so as to remove a residue remaining on the surface of the image carrier; an attaching member that includes a first attachment piece to which a base end of the cleaning blade member is attached, and a second attachment piece which is provided so as to intersect the first attachment piece at a predetermined angle; a housing member to which one of the first attachment piece and the second attachment piece is fixed at both ends along a longitudinal direction thereof; and an external force exerting member that exerts an external force in a direction which intersects a surface of the other one of the first attachment piece and the second attachment piece, which is not fixed to the housing member.

Abstract: A cleaning device includes a cleaning blade that contacts a surface of a member to be cleaned to remove a residue remaining on the surface of the member to be cleaned, and that includes multiple layers, wherein a leading end portion of the cleaning blade shifts in a separating direction from the surface of the member to be cleaned due to a difference in thermal expansion property among the multiple layers when temperature rises.

Abstract: A cleaning member includes a cleaning part whose one end portion comes into contact with a surface of an image carrier, and a supporting part that supports the cleaning part and applies a force for pressing the one end portion of the cleaning part to the surface of the image carrier, wherein a surface of a first portion including the one end portion of the cleaning part is bonded to the supporting part with a first adhesive layer, and a surface of a second portion including the other end portion opposite to the one end portion of the cleaning part is bonded to the supporting part with a second adhesive layer having a Type-A durometer hardness which is lower than that of the first adhesive layer.
