20120251185 | DEVELOPING DEVICE - A developing device includes a developer carrying member for carrying a developer; a first feeding chamber for feeding along the developer carrying member to supply the developer to the developer carrying member and for collecting the developer, after being subjected to development; a second feeding chamber, connected to the first feeding chamber, for foaming a circulating path with the first feeding chamber; and a screw member rotatably provided in the first feeding chamber. In a region where the screw member opposes at least a developing region with respect to a rotational axis direction of the developer carrying member, the screw member includes a first helical portion having a helix direction of feeding the developer in the same direction as a circulation direction of the circulation path and a second helical portion having a helix direction opposite to the helix direction of the first helical portion. | 10-04-2012 |
20120269555 | DEVELOPING DEVICE - A developing device includes a developer carrying member for carrying a developer; a circulation path along which the developer is circulated; a carrier supplying portion; a discharge opening, provided in the circulation path, through which a portion of the developer is to be overflowed and discharged; and a feeding member comprising a rotation shaft and a blade portion including a helical portion. An outer diameter of the blade portion formed in a first region including at least a portion opposing the discharge opening is smaller than that in a second region adjacent to the first region with respect to a rotation shaft direction. A smaller average angle formed between the rotation shaft and a developer feeding surface of the blade portion in the first region is smaller than that in the second region. | 10-25-2012 |
20130287449 | DEVELOPING DEVICE AND IMAGE FORMING APPARATUS - A developing device includes a developing sleeve, a magnet roller mounted in the developing sleeve, a first conveying screw feeding a developer to the developing sleeve, and a regulating blade regulating a layer thickness of the developer. The developing device further includes a guide member that backs up the developer from the first conveying screw at an upstream side of the regulating blade based on a rotational direction of the developing sleeve and that forms a buffer portion temporarily containing the developer between the regulating blade and the guide member. The guide member is installed so that a direction of a resultant force of a magnetic force and a gravitational force acting on a carrier particle becomes a direction away from a surface of the guide member on a facing surface of the guide member which is opposite to the regulating blade. | 10-31-2013 |
20150071683 | DEVELOPING DEVICE - A developing device includes: a developer carrying member; a first chamber; a second chamber; a partition wall; a communicating portion; and a feeding member, provided rotatably in the first chamber, for feeding the developer in the first chamber. In a circulation path, the feeding member includes a first region corresponding to a developer coating region of the developer carrying member and a second region, provided downstream of the first region with respect to a feeding direction of the feeding member, corresponding to a region outside the developer coating region of the developer carrying member. Feeding power per unit driving time of the feeding member is set at a smaller value in the first region than in the second region. | 03-12-2015 |

20150338780 | IMAGE FORMING APPARATUS - An image forming apparatus includes: a developer carrying member (sleeve) including a magnet and grooves; and an image bearing member (drum). The electrostatic image on the drum is developed with a developer. When a linear speed of the sleeve is Vs, a linear speed of the drum is Vd, a peripheral speed ratio of the sleeve to the drum is α=Vs/Vd, a radius of the sleeve is Rs, a radius of the drum is Rd, a distance of a rectilinear line connecting a most upstream point and a most downstream point in the developing region with respect to the circumferential direction is Lnip, a pitch of the grooves of the sleeve is p, and an arbitrary natural number is n, the following relationship is satisfied: | 11-26-2015 |
20160085197 | IMAGE FORMING APPARATUS - An image forming apparatus includes an image bearing member, a developing device, a supplying device, and a control unit. The image bearing member bears a latent image. The developing device develops the latent image with a toner. The supplying device supplies toner to the developing device. The control unit executes a discharge operation to consume toner transferred onto the image bearing member from the developing device without transferring the toner onto a recording medium. The control unit executes the discharge operation where first deterioration integrated information exceeds a first executing threshold, and where second deterioration integrated information exceeds a second executing threshold that is larger than the first executing threshold. The control unit acquires the first deterioration information based at least a first deterioration threshold, and acquires the second deterioration information based on at least a second deterioration threshold that is larger than the first deterioration threshold. | 03-24-2016 |
