    Abstract: 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.

    Abstract: An image forming apparatus including a conveyance unit to convey a transfer medium, a first image forming unit to form a monochrome image transferred at a first transfer position onto the transfer medium, and a second image forming unit disposed downstream from the first image forming unit in a direction of conveyance of the transfer medium, including an intermediate transfer body to form a multi-colored toner image on the intermediate transfer body. The multi-colored toner image is transferred onto the transfer medium at a second transfer position. The conveyance unit is separated from the intermediate transfer body at the second transfer position in a monochrome mode to form the monochrome image using only the first image forming unit, and contacts the intermediate transfer body at the second transfer position in a full-color mode to form a full-color image using both the first and second image forming units.
