Title (EN) DEVELOPMENT CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS USING THE SAME
(FR) CARTOUCHE DE DÉVELOPPEMENT ET APPAREIL DE FORMATION D'IMAGE ÉLECTROPHOTOGRAPHIQUE L'UTILISANT
Abstract:
(EN) A development cartridge attachable to and detachable from a main body of an image forming apparatus includes a photosensitive unit including a photosensitive drum, a developing unit including a developing roller and rotatably coupled to the photosensitive unit with respect to a hinge axis, a driving gear configured to rotate in a first direction for a printing operation or a second direction opposite the first direction, a driving member positioned coaxially with the driving gear and configured to be rotated by the driving gear, a first one-way clutch configured to connect the driving member with the driving gear only when the driving gear rotates in the second direction, and a first moving member configured to be connected to the driving member so as to reciprocate between a first location where a development nip is formed and a second location where the development nip is released.
(FR) L'invention concerne une cartouche de développement pouvant s'attacher à un corps principal d'un appareil de formation d'image et se détacher de ce dernier, comprenant une unité photosensible comportant un tambour photosensible, une unité de développement comprenant un rouleau de développement et couplée de manière rotative à l'unité photosensible par rapport à un axe d'articulation, un engrenage d'entraînement configuré pour tourner dans une première direction pour une opération d'impression ou une seconde direction opposée à la première direction, un élément d'entraînement positionné de manière coaxiale à l'engrenage d'entraînement et configuré pour être tourné par l'engrenage d'entraînement, un premier embrayage unidirectionnel configuré pour relier l'élément d'entraînement à l'engrenage d'entraînement uniquement lorsque l'engrenage d'entraînement tourne dans la seconde direction, et un premier élément mobile configuré pour être relié à l'élément d'entraînement de façon à réaliser un mouvement de va-et-vient entre un premier emplacement, dans lequel une pince de développement est formée, et un second emplacement dans lequel la pince de développement est relâchée.
