PROBLEM TO BE SOLVED: To suppress cohesion of a developer due to contacting between a conveyance member conveying a developer and a wall surface of a flow passage as compared with a configuration in which a second conveyance member of a second conveyance path located side by side with a first conveyance path is equal in length to a first conveyance member of the first conveyance path.SOLUTION: A development device 60 has a first conveyance path 76 and a second conveyance path 77. The first conveyance path 76 conveys a developer G including toner T and a carrier C in a Z direction through rotation of the first conveyance member 66 opposed to a development roll 64. The second conveyance path 77 comprises a first flow passage 78 and a second flow passage 82, and second conveyance members 68, 72. The first flow passage 78 and second flow passage 82 are each shorter than the first conveyance path 76, and ends thereof are connected to each other so as to move the developer G such that a developer G having flowed in from one end of the first conveyance path 76 flows in the other end of the first conveyance path 76.SELECTED DRAWING: Figure 3 |
