PURPOSE:To provide a developing agent conveyor, which is compact in construction, by feeding a magnetic developing agent to guide means with the use of conveyor means having a magnetic source so that the developing agent may be pushed upward. CONSTITUTION:The developing agent, which is removed by means of an elastic cleaning blade 2, is attracted without scattering to the surface of a magnetic roller 3 by the magnetic force thereof so that it is moved between magnetic rollers 3 and 4 having opposite polarities by the rotations of the roller 3. The developing agent caught on the roller surfaces are moved upward by the opposite polarities irrespective of the quantity of the developing agent which is stored in a guide member 6. The developing agent thus moved is separated from the roller surfaces into the guide member 6 by the actions of scrapers 71 and 72. The developing agent is moved upward without being allowed to fall down by the actions of the developing agent, which is supplied subsequently, until it is stored in its reservoir 8. |
