Abstract
In a developing device including a developer tank having a developing area tank and an agitating tank, a first agitating member, a second agitating member, a toner hopper, and a toner storing container, a toner replenishing port is formed in an agitating tank, and two flows of the developer are produced by a rotation of the first agitating member provided with a first agitating blade and a second agitating blade, from both ends of a longitudinal direction of the developer tank to a vicinity of the toner replenishing port. These two flows collides with each other in a vicinity of the toner replenishing port to produce a pulsation flow of the developer from the toner replenishing port into the toner storing container through the toner hopper.
