Abstract
An image forming apparatus has a toner carrier and a toner passing control having a plurality of toner passing holes for controlling passage of a toner. The toner passing control has upstream side secured, the downstream side extended by a spring, and is contacted with a stay on the downstream side of the contact point with the toner carrier, so that corrugation deformation is prevented. A vibrating plate and an ultrasonic vibration generator are coupled through a coupling portion, thereby relative displacement between the vibrating plate and the ultrasonic vibration generator is allowed. A detachable toner cartridge is formed by integrating a developing roller and a toner storing container.
