Abstract
(EN) A bracket (30) to mount a charge roller (26) and a blade (40) against a photoconductive drum (14) within an image forming apparatus (100). Bracket (30) may comprise a pair of guides (31) that extend outward to receive the ends of the charge roller (26). A biasing device (62) may be positioned to bias the charge roller (26) against the photoconductive drum (14). The guides (31) may include an opening sized to allow the charge roller (26) to move and maintain contact with the photoconductive drum (14). A mounting surface (50) may be positioned on the bracket (30) for receiving adhesive to mount the blade (40). In one embodiment, the bracket (30) is constructed of a molded thermoplastic polymer.
(FR) L'invention concerne un support (30) de montage d'un rouleau (26) de charge et d'une lame (40) contre un tambour photoconducteur (14) dans un appareil (100) de formation d'image. Le support (30) peut comprendre une paire de guides (31) s'étendant vers l'extérieur de manière à recevoir les extrémités du rouleau (26) de charge. Un dispositif (62) de polarisation peut être positionné pour polariser le rouleau (26) de charge contre le tambour photoconducteur (14). Les guides (31) peuvent comprendre une ouverture dont la dimension permet au rouleau (26) de charge de se déplacer et de maintenir le contact avec le tambour photoconducteur (14). Une surface (50) de montage peut être positionnée sur le rouleau (30), destinée à recevoir un adhésif pour le montage de la lame (40). Dans un mode de réalisation, le rouleau (30) est fait d'un polymère thermoplastique moulé.
