PURPOSE:To prevent a developer from scattering out by providing a guide member which guides magnetic particles supplied from a 1st storage part to a developer container to a magnetic shielding means side. CONSTITUTION:A magnetic particle circulation limiting member 26 is provided inside the container 21 of a blade 24 to limit the circulation area of particles in the container 21. Further, the plate type guide member 42 which guides the magnetic particles 27 from the magnetic particle storage part 43 to the magnetic seal 31 is provided above a developing sleeve 22 in the container 21. Thus, the guide member 42 is provided to guide the magnetic particles 27 to the side of the magnetic seal member 31 by the guide member 42 when the magnetic particles 27 are supplied from the magnetic particle storage part 43 to the developer container 42. Consequently, the magnetic particles are guided to between the magnetic field seal 31 and developing sleeve 22 and no gap is formed at the part, so the magnetic particles 27 are not held by the seal member 31, etc., to form a gap with the sleeve 22, thereby preventing toner 28 which is supplied next from scattering out of the container 21. |
