Abstract

The present invention relates to a developer storage container, an image forming unit and an image forming apparatus, which prevent developer from splashing and polluting the periphery of an opening part when the developer storage container is detached from the body of the image forming unit. The developer storage container comprises a developer storage container housing, a storage part formed in the developer storage container housing for storing the developer, the opening part formed in the developer storage container housing for supplying the developer in the storage part to the outside of the developer storage container housing, and an opening / closing part used for opening and closing the opening part. A recess is formed in the portion, which is opposite to the opening part, of the opening / closing part, so that the developer will not be attached to the outer peripheral surface of the opening / closing part. Therefore, the developer is prevented from splashing and polluting the periphery of the opening part when the e developer storage container is detached from the body of the image forming unit.

Description

technical field [0001] The present invention relates to a developer container, an image forming unit, and an image forming apparatus. Background technique [0002] Conventionally, image forming apparatuses such as printers, copiers, facsimile machines, and multifunction peripherals, such as printers, have image forming units, LED optical heads, transfer units, fusers, and the like. The image forming unit has a main body of the image forming unit, that is, an image forming unit main body, and a toner cartridge on which the toner cartridge is detachably provided as a developer container. The main body of the image forming unit is provided with a photosensitive drum, a charging roller, a developing roller, a developing blade, a toner supply roller, a cleaning blade, etc., and a toner serving as a developer is stored in the toner cartridge. [0003] In the printer, the surface of the photosensitive drum uniformly charged by the charging roller is exposed by the LED head to form...
