    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.

    摘要: A carrier for a dry two-component developer, includes a core material and a silicone-modified acrylic resin layer coated on the surface of the core material, the silicone-modified acrylic resin layer including a silicone-modified acrylic resin, with the ratio of the percentage transmission of infrared spectrum Si--O stretching vibrations (T.sub.Si) of the silicone-modified acrylic resin layer to the percentage transmission of infrared spectrum C.dbd.O stretching vibrations (T.sub.C) thereof, T.sub.Si /T.sub.C, being at least 1.0. The silicone-modified acrylic resin layer can be made from a water-soluble synthetic resin solution containing a silicone macromonomer (A) with a vinyl group being introduced into one terminal thereof, and a vinyl monomer (B) which is copolymerizable with the silicone macromonomer (A), with the molecular weight of the silicone macromonomer (A) of the silicone-modified acrylic resin being in the range of 1,000 to 10,000. Methods of producing such carriers are provided.
