    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 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 developing apparatus contains a developer for developing a latent image formed on an image carrier. The developing apparatus includes a developer carrier disposed opposite to the image carrier; a developer regulating member regulating an amount of the developer carried by the developer carrier; and a developer circulating unit transporting the developer in a circulating path. The developer circulating unit includes a rotatable first transport member supplying the developer to the developer carrier while transporting the developer in a horizontal direction, a shielding member preventing the developer separated from the developer carrier from flowing back toward the first transport member, and a rotatable second transport member collecting the developer separated from the developer carrier while transporting the developer in the horizontal direction. A distance between the second transport member and the developer carrier is greater than a distance between the first transport member and the developer carrier.
