Patent ID: 8805233

Claim:
A cleaning device comprising: a developer removing member that has a substantially long plate shape, one edge of the developer removing member that extends in a long-side direction coming into contact with a surface of an image carrier, the developer removing member removing developer residues from the surface of the image carrier while the image carrier is rotating in a short-side direction; a supporting member that is in contact with a surface of the developer removing member opposite another surface of the developer removing member that faces the image carrier, the supporting member supporting the developer removing member in the long-side direction such that the developer removing member extends beyond the supporting member on a side thereof having the one edge; a developer collecting member that has an opening, the opening being substantially long in the long-side direction with a smaller length in the long-side direction than the developer removing member, the developer collecting member being configured such that the one edge of the developer removing member is positioned in a central portion of the opening in the short-side direction and such that portions defining one edge of the opening extending in the long-side direction and two edges of the opening extending in the short-side direction, respectively, face a combination of the supporting member and the developer removing member, the developer collecting member collecting, via the opening, the developer residues that have been removed from the image carrier; a sealing member that is provided between the combination of the supporting member and the developer removing member and the portions defining the one edge of the opening extending in the long-side direction and the two edges of the opening extending in the short-side direction, the sealing member sealing any gaps produced therebetween; and an adhesion preventing member provided in each of the portions defining the two respective edges of the opening extending in the short-side direction, the adhesion preventing member being interposed between the sealing member and the developer removing member and preventing the developer removing member and the sealing member from adhering to each other.
