PROBLEM TO BE SOLVED: To obtain a uniform distribution of concentration of unused developer and recovered developer so as to feed them to stick to a developing roll by the way each developer. SOLUTION: In this developer-feeding device and image-forming device, the recovered developer and the unused developer are fed to a central area 53 of agitating members 35 to 37 corresponding to the central part of the developing roll in the direction of a shaft. Each developer fed to the central area 53 is transported in the direction of the developing roll 34 by the agitating action of the agitating members 35 to 37, and at the same time, is transported dispersed in the vertical direction. The ratio of mixture of each developer stuck to the developing roll 34 is made into a more uniform condition, by having particles of each developer exchange places in each of the directions. |
