  • Patent number: 9310714
    Abstract: 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.

  • Patent number: 9298125
    Abstract: 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.
