Description
Technical field
The present invention relates to a kind of gear drive that is used for developing box, also relate to a kind of developing box simultaneously with this gear drive.
Background technique
The imaging forming device of electro photography like laser printer, is a kind of electrofax principle of utilizing, at least through overcharge, processes such as exposure, development, transfer printing, photographic fixing and cleaning, form medium (for example paper) at image and go up the equipment that forms image.
In charging process,, utilize and the surface of photosensitive element (for example sensitometric drum) is filled with predetermined electric charge uniformly like coronal discharge mode or charging roller through charging unit; In exposure; Optionally exposure is carried out on photosensitive element surface to filling even predetermined charge with; Because the light sensitive characteristic of photosensitive element; To be grounded cancellation by the electric charge in the zone of exposure, like this, the photosensitive element surface forms an electrostatic latent image that distribution characterized by electric charge corresponding to institute's desire formation image after exposure; At developing process; Through developing device (for example developer roll) the developer that is used to form visual image (for example carbon dust); The electrostatic latent image district on photosensitive element surface is delivered in the effect of mating reaction power (for example electric field force), and it is visual to make that above-mentioned electrostatic latent image obtains; In transfer process, transfer to image to the developer on the electrostatic latent image on photosensitive element surface through transfer device (for example transfer-roller) and form on the medium; At fixing, be secured in the developer of transferring on the image medium on the image formation medium through fixing apparatus.At cleaning course, through cleaning device (for example cleaning doctor) developer of photosensitive element remained on surface is wiped off, in order to avoid get into next imaging cycle, cause print defect.
The Developing cartridge gear drive of existing technology generally comprises photosensitive drum gear; The developer roll gear, powder feeding roller gear, puddle support gear; Wherein photosensitive drum gear receives external motivating force and rotates, puddle support gear and powder feeding roller gear engagement and receive rotary driving force.
In conventional developing box, developer roll and powder feeding roller all are provided with near bottom, powder storehouse, like this, following two kinds of problems will occur:
1. ought see from the side; Powder storehouse height is during much larger than its width, if the powder feeding roller gear with puddle support direct geared engagement and transmit rotary driving force, then limited position that puddle support installs also must be near bottom the powder storehouse; Therefore; If with the width of puddle support upper blade be provided with too little, the developer that is positioned at top, powder storehouse can not be stirred the frame blade naturally and touch, thereby must cause the Yu Fenliang in the powder storehouse to increase; If with the width of puddle support upper blade be provided with too big; The crooked deformability of mixing blade must be limited, when the puddle support blade rotates to bottom, powder storehouse, then can hinder the continuation rotation of puddle support; And cause the moment of torsion of puddle support to increase, be unfavorable for powder feeding on the contrary.
2. ought see from the side; When the width in powder storehouse was excessive, for guaranteeing specific velocity ratio between powder feeding roller gear and the puddle support gear, the number of teeth of two gears and size must be restricted; In addition; The width neutral position, powder storehouse that the puddle support mounting point preferably is provided with if powder feeding roller gear and puddle support gear continue direct engagement, will inevitably have influence on the powder feeding effect.
