Abstract
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.
