Developing device, process cartridge, and image forming apparatus incorporating same
A developing device includes a casing having an opening, the casing to contain developer, and a developer bearer including a magnetized range to cause developer to stand on end on a surface of the developer bearer and an end range outside the magnetized range in a longitudinal direction of the developer bearer. The developer bearer is disposed in the casing and partly exposed from the opening with a casing gap secured between the surface of the developer bearer and an inner face of the casing. The developer bearer generates, by rotation, sucked-in airflow to collect a floating toner from the opening into the casing, and the casing gap is smaller in the end range than the magnetized range.
