Abstract

A developer supply device includes a shell, a cavity for storing a developer is formed in the shell; a powder outlet communicated with an inner cavity of the shell is formed in the shell; the developer in the shell flows out of a supply container and enters imaging equipment; the developer supply device further includes a driving gear train arranged on the shell and a sealing assembly connected with the driving gear train. The driving gear train is connected with a driving part in the image forming device after a developer supply container is installed in the imaging equipment, and when the driving gear train is driven by a driving device to rotate, the sealing assembly acts along with the action of the driving gear train to control opening and closing of the powder outlet. The driving gear train and the sealing assembly are arranged, the powder discharging mode is improved, and adverse faults such as jamming after installation are avoided in any step and any occasion.

Description

technical field [0001] The invention relates to the field of developer supply, in particular to a developer supply device. Background technique [0002] Currently, an image forming apparatus such as an electrophotographic copier or a printer uses a developer in the form of fine particles, which is supplied into the image forming apparatus using a developer container when the developer in the main assembly of the image forming apparatus is used up. [0003] In the existing equipment, the developer is filled into the developer replenishment container through the powder filling port, and the developer replenishment container is put into the image forming device, but when the developer replenishment container supplies the image forming device, image formation is required. The device pushes down one of the gears, so that the powder outlet is opened to achieve the purpose of powder feeding. However, during the opening process, it is prone to jamming due to increased friction, and...
