IPC: G03G15/08
Filed: 1987-03-23
Abstract: PURPOSE:To permit conveyance of the developer remaining in a housing part toward a developing roller without freshly providing a conveying member to the inside of a developing device and to reduce cost by forming a guide part having a surface inclined at a prescribed angle or surface having a prescribed radius of curvature to the bottom part of the developing device body. CONSTITUTION:The developing device 41 is provided in the prescribed position of an upper unit which is freely openable and closable with respect to a base part unit. The guide part 412 having the surface inclining at the prescribed angle is formed on the bottom of the housing part 411 for housing the developer G in the developing device 41. The developing device 41 inclines integrally upward as well when the upper unit is opened because of paper jamming or the like. The developer G remaining in a pool part 4111 in the position lower than the height of the guide part 412 in this state flows toward the left side of the guide part 412, i.e., a developer recovering roller 414. The developer G is automatically held near the aperture on the left side of the guide part 412 so as to be conveyed toward the roller 413 side when the upper unit is returned again to the home position.
