摘要： A developing device of the type developing a latent image formed on an image carrier with a two-ingredient type developer, i.e., a mixture of toner and magnetic carrier particles is disclosed. The device is operable without a sophisticated toner content control mechanism or a sophisticated developer agitating and conveying mechanism, and is capable of obviating various problems ascribable to the increase in the toner content of the developer at the opposite end portions of a developer carrier. For this purpose, the device restricts the movement of a developer present on the developer carrier in the direction substantially perpendicular to the direction in which the developer carrier conveys the developer.

摘要： A developing device for an image forming apparatus and capable of automatically controlling the toner content of a developer is disclosed. Even when the toner content of the developer deposited on a developer carrier and being conveyed toward a developing position becomes irregular due to some cause, the developer is prevented from remaining at the developing position. This guarantees a desired developing position despite the automatic toner content control. In addition, the toner content of the developer is prevented from increasing at portions adjoining the opposite ends of the developer carrier.

摘要： A developing device for an image forming apparatus and of the type using a developer consisting of toner and magnetic particles is disclosed. While a developing sleeve conveys the developer deposited thereon, toner is automatically replenished to the developer from a toner hopper via an opening formed in the hopper due to the movement of the developer. At the same time, the toner introduced into the developer is charged by friction. A developer storing member includes a penthouse portion. A projection protrudes from the surface of the penthouse portion facing the developing sleeve toward the sleeve and extends in the direction perpendicular to the direction in which the sleeve conveys the developer. The developer forms on the sleeve a layer having stable toner content and stable toner charge without resorting to a sophisticated toner content control mechanism.

摘要： In an image forming apparatus, a developing device has a developing sleeve accommodating a magnet roller therein, and a doctor for regulating the amount of developer to be conveyed to a developing position. When the developing sleeve is rotated, the part of the doctor shaved off by the doctor from the sleeve is moved in a developer storing section to a toner replenishing opening formed in a toner storing section. Then, this part of the developer is returned to the doctor along the surface of the sleeve via the toner replenishing opening. The developer consists of a first developer containing a first carrier and deposited in a layer on the surface of the sleeve, and a second developer containing a second carrier different from the first carrier and stored in the developer storing section in such a manner as to contact the first developer deposited on the sleeve. The first carrier has a higher charging ability than the second carrier. The device does not need a toner replenishing mechanism or a toner concentration sensor and has, therefore, a miniature and inexpensive construction. In addition, the device is applicable even to a high-speed image forming apparatus.

摘要： In a developing device for an image forming apparatus and of the type using a developer consisting of toner and magnetic carrier, a toner hopper has an opening for replenishing toner stored therein. The developer is regulated by a doctor blade to form a thin layer on a developing sleeve. The developer scraped off by the doctor blade is introduced into a developer storing chamber and caused to move toward the opening of the hopper due to its own internal pressure and gravity. The developer from the hopper is returned toward the doctor blade along the surface of the sleeve. The developer on the sleeve and regulated by the doctor blade is conveyed to a developing position where the sleeve faces an image carrier. The toner contained in the developer is a magnetic toner. When the toner concentration of the developer has reached an upper limit, a space or gap exists in the developer storing chamber.
