<p>A development device (3) includes a development casing (301), a developer bearer (302), a first developer conveyance member (304) to supply developer to the developer bearer (302), a second developer conveyance member (305) to transport developer axially, and a partition (306) dividing separating a supply channel (340) from a collecting channel (350). The supply channel (340) includes a conveyance area (341) and a buffer area (342) disposed adjacent to the conveyance area (341) in a direction perpendicular to an axial direction to temporarily retain developer and midway in the developer conveyance direction inside the supply channel (340), and an upstream end face (342f) defining an upstream end of the buffer area (342) is inclined relative to the axial direction to draw away from the conveyance area (341) downstream in the developer conveyance direction.</p> |
