FIELD: instrument making.

SUBSTANCE: invention relates to a cartridge detachably mounted on main assembly of an electrophotographic image forming device and to a unit for use with electrophotographic image forming device. Cartridge detachably mounted on main assembly of an image forming device comprises a rotating element, a blade element, which includes rubber part in contact with said rotating element, and a metal plate part to support rubber part, housing made from polymer material to support said blade element and sealing element passing in direction crossing axial direction of said rotating element, arranged on said housing to come into contact with said rubber part and with said metal plate part, wherein said sealing element is formed on said housing by means of injection moulding to seal gap between said blade element and said housing. Technical result consists in prevention of leakage of residual toner from gap between cartridge housing and stripper beyond process cartridge and in vertical sealants for sealing gap between cartridge housing and stripper in contact with stripper in terminal along length of cartridge housing parts, as well as in cartridge and unit, which can improve assembly when sealing element is assembled with housing by means of automatic machine and also can implement assembly with high accuracy to improve sealing characteristics for toner.
