摘要： A developing device includes a developing roller, a cover to cover the developing roller from above the developing roller, a filter to cover a vent of the cover to filter air and collect toner passing through the vent, and a pressing member engaged with the cover in which the filter is installed. The cover includes a projecting support to support the filter. The pressing member holds the filter between the pressing member and the cover. The projecting support is projected from one end toward the other end of the vent in a transverse direction of the vent at a part of the cover in a longitudinal direction of the developing roller to block the vent, and cantilevered on the one end. A gap is provided between a tip of the projecting support and an inner edge of the cover on the other end.

摘要： An image forming apparatus includes a driving device, a transfer body, a toner detector, an error notification device, and a controller. The toner detector detects, at a preparation running and while the driving device drives a latent image bearer, one of a toner adhesion amount at a background portion of the latent image bearer and a toner adhesion amount at a background corresponding region of a transfer body. The error notification device notifies a user of an error with the toner adhesion being equal to or greater than a predetermined threshold value. The driving device stops only a developer bearer after driving both the latent image bearer and the developer bearer at the preparation running, but before a trailing edge of a detection target region of one of the background portion of the latent image bearer and the background corresponding region advances to an opposite position to the toner detector.

摘要： An image forming apparatus includes a latent image bearing member, a charging unit, a charging power source, a latent image writing unit, a development unit, a transfer unit, a toner detector, and a controller. The controller causes a background fog pattern to be formed on a surface of the latent image bearing member. In addition to the background fog pattern, the controller causes a latent image to be developed to form a toner image used for position identification on the surface of the latent image bearing member. The controller identifies a time when the toner image used for position identification has entered a detection range of the toner detector based on a change in outputs of the toner detector to determine a time when each of sections of the background fog pattern enters the detection range based on the identified time.
