DEVELOPER STORAGE DEVICE, DEVELOPING DEVICE, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS

Document Type and Number:

Japanese Patent JP2023062824

Kind Code:

A

Abstract:

To sufficiently dissipate heat that is generated due to slide contact of seal members with a rotation shaft of rotating members, thereby increasing processability.SOLUTION: A developing device 26 (developer storage device) storing developer is provided with conveying screws 26b1, 26b2 (rotating members) that are provided with a rotation shaft 261, bearings 26m that are formed of a metal material and rotatably hold the rotation shaft 261, holding members 26n that each have an inner diameter part 26n1 to which the bearing 26m is press fit, and seal members 26t that each are in slide contact with an outer peripheral surface of the rotation shaft 261 at a position inside the developing device 26 with respect to the bearing 26m. The seal members 26t are each in contact with an inside end face of the bearing 26m at the inner diameter part 26n1 of the holding member 26n.SELECTED DRAWING: Figure 4
