    摘要: At least a photosensitive drum 2 and charge roller 9 are attached to a unit 8 so that the photosensitive drum 2 and charge roller 9 can be freely attached to and detached from an apparatus body 1 in unison with the unit case 8, and the charge roller 9 can be freely brought into and out of contact with the surface of the photosensitive drum 2. The apparatus body 1 is provided with pressure cams 5a and 5b adapted to cause the charge roller 9 to be brought into and out of contact with the surface of the photosensitive drum 2.

    摘要: A device for cleaning a wire of a corona discharge type charger installed in an electrophotographic copier or similar image recording apparatus such as a charger for charging a photoconductive element, a transfer charger or a separation charger. The device includes a pair of cleaning pads which clean the wire by individually holding diametrically opposite portions of the periphery of the wire, i.e. a portion which faces the surface of the photoconductive element to be charged and a portion which is remote from the surface of the same element. The cleaning pads act on the wire only when the pads and the wire are moved in one predetermined direction relative to each other.
