    摘要： A developing device includes a developer bearer, a magnetic field generator provided inside the developer bearer, a casing including an opening to partly expose a surface of the developer bearer, and a lateral end cover to cover an axial end portion of the exposed surface of the developer bearer. The lateral end cover includes a wide portion extending more to an axial inner side of the developer bearer than a downstream portion of the lateral end cover positioned downstream from the wide portion in a direction of rotation of the developer bearer. A downstream end of the wide portion is downstream from an upstream end of the development range in the direction of rotation of the developer bearer.

    摘要： A development device is operable in multiple different speed modes and includes a developer bearer to carry developer, a developer regulator to adjust an amount of developer carried on the developer bearer, and multiple developer conveyance members disposed facing the developer bearer to transport developer in a longitudinal direction to circulate developer inside the development device. The multiple developer conveyance members including a first developer conveyance member to supply developer to the developer bearer and a second developer conveyance member to transport developer collected from the developer bearer. The development device executes developer amount balance adjustment in which a driving velocity of at least the multiple developer conveyance members is increased from a driving velocity in a lower-speed mode for a predetermined period after image development in the lower speed mode is completed and before image development in a higher speed mode is started.

    摘要： A developing device includes a developer bearer, a development casing in which a developer conveyance channel is formed facing the developer bearer through a communicating area, a developer supply member disposed in the developer conveyance channel, a developer regulator disposed facing a lower portion of the developer bearer to adjust an amount of developer carried on the developer bearer, and a sheet member that is removably installed to seal the communicating area and passes through a gap between the developer regulator and the developer bearer and an opening formed in the development casing. A first end of the sheet member is retained downstream from the gap in a direction of rotation of the developer bearer, and the sheet member is fixed to the development casing at a position across the communicating area from the first end with a second end positioned outside the development casing.
