    摘要： A development device includes a development casing, a developer bearer, a first developer conveyance member to supply developer to the developer bearer, a second developer conveyance member to transport developer axially, and a partition dividing an interior of the development casing into a supply channel and a collecting channel via which developer received from a downstream end portion of the supply channel is forwarded to an upstream end portion of the supply channel. The supply channel includes a conveyance area and a buffer area disposed adjacent to the conveyance area in a direction perpendicular to an axial direction to temporarily retain developer and midway in the developer conveyance direction inside the supply channel, and an upstream end face defining an upstream end of the buffer area is inclined relative to the axial direction to draw away from the conveyance area downstream in the developer conveyance direction.
