摘要： A developing device for an image forming apparatus and using a one component type developer. The developer is transferred from a developer supply member to a developer carrier which are so rotated as to move in the same direction at a position where they contact each other. This prevents the developer from a toner storing section from directly reaching part of the developer carrier having moved away from the contact position despite the movement of the developer supply member. Conductive portions connected to ground and dielectric portions each having a small area are distributed regularly or irregularly on the surface of the developer carrier. Such a surface of the developer carrier is charged by friction by the developer supply member with the result that a great number of microfields are formed in the vicinity of the developer carrier. The microfields allow only the developer sufficiently charged by friction at the contact position to form multiple layers on the surface of the developer carrier. Consequently, the toner with a desired amount of charge and containing a minimum of uncharged toner can form multiple layers on the developer carrier and is transferred to an image carrier.
摘要翻译：一种用于图像形成装置和使用单组分型显影剂的显影装置。显影剂从显影剂供应构件转移到显影剂载体，显影剂载体如此旋转以在它们彼此接触的位置沿相同方向移动。这防止显影剂供应构件的移动而使调色剂存储部分的显影剂直接到达显影剂载体的已远离接触位置的部分。连接到接地的导电部分和各自具有小面积的电介质部分规则地或不规则地分布在显影剂载体的表面上。显影剂载体的这种表面由显影剂供应构件的摩擦带电，结果是在显影剂载体附近形成大量的微场。微场仅允许在接触位置处通过摩擦力充分充电的显影剂在显影剂载体的表面上形成多个层。因此，具有期望量的电荷并且含有最少不带电调色剂的调色剂可以在显影剂载体上形成多个层并被转印到图像载体上。

摘要： A developing device applicable to an electrophotographic copier, facsimile transceiver, laser printer or similar image forming apparatus and having a developing roller for carrying a nonmagnetic single component type developer, i.e., a toner and a toner supply roller for supplying the toner to the developing roller. The developing roller has dielectric portions and conductive portions each having a small area and distributed together on the surface thereof. The conductive portions are connected to ground and have a volume resistivity of 10.sup.6 .OMEGA.cm or below. The toner supply roller is made up of a metallic core and an elastic foam layer provided on the core and having conductivity and a predetermined frictional charging characteristic. A potential difference is set up between the developing roller and the toner supply roller to generate electric fields which act on a frictionally charged toner as a force directed from the toner supply roller toward the developing roller. Micropores existing in the surface of the toner supply roller have a depth and a size selected in such a manner as not to disturb microfields formed by frictional charges deposited on the dielectric portions. The two different kinds of electric fields exist together to enhance the supply of charged toner. To eliminate leaks between the two rollers, one of the rollers is semiconductive while the other roller is conductive, and use is made of a toner whose resistance is greater than predetermined one.

摘要： In an image forming apparatus, a rotary developing device effects development by revolving a plurality of developing sections around a rotary shaft until any one of them reaches a developing position where it faces an image carrier. Cartridges are respectively mounted to hoppers included in the developing sections. Guides are provided on the inner periphery of each cartridge in order to guide toner, moving due to the revolution or the developing device, toward a toner outlet formed in the cartridge. Even when the amount of toner remaining in the cartridge is small, the entire toner is replenished into the associated hopper and fully consumed.

摘要： A developing apparatus having a rotatable toner carrier for transporting a toner to a developing region where it faces an image carrier on which a latent image has been electrostatically formed. The surface of the toner carrier is constituted by a mixture of conductive surface portions and dielectric surface portions and selectively holds a charge to form microfields. The toner having been charged is electrostatically deposited on the toner carrier by the microfields and transported to the developing region as the toner carrier moves. In the developing region where the toner carrier and the image carrier face each other while defining a developing gap therebetween, the toner electrostatically flies from the toner carrier to the latent image formed on the image carrier to thereby develop it.

摘要： A developing device incorporated in an image forming apparatus and including a developing roller or similar developer carrier for transporting a developer to a developing region where it faces an image carrier, so as to develop a latent image electrostatically formed on the image carrier. The developer carrier has a first and a second substance different in charging characteristic from each other and exposed to the outside on the surface of the developer carrier in a regular or irregular pattern. At least one of the first and second substances is charged to predetermined polarity on the surface of the developer carrier to form a great number of microfields. Alternatively, the developer carrier may have a conductive base and a surface layer provided on the base and constituted by a conductive substance in which insulating particles are dispersed. At least the insulating particles are charged on the surface of the developer carrier to form a number of microfields. The movement of the developer is controlled by an electric field determined by a relation of a potential deposited on the image carrier, an electric field ascribable to the bias applied from a bias applying source, and an electric field developed on the developer carrier.
