    摘要: A developing method of the present invention is practicable with a developing unit (1) of the type including a rotatable, nonmagnetic sleeve (7) and a rigid metering member (9). A two ingredient type developer made up of magnetic carrier grains and toner grains is magnetically deposited on the sleeve (7). The metering member (9) meters the amount of the developer deposited on the sleeve (7). The sleeve (7) has surface roughness Rz ranging from 5 µm to 20 µm. The carrier grains each are covered with a coating layer containing at least binder resin and grains. The ratio of the diameter D of the individual grain contained in the coating layer to the thickness h of the binder resin layer lies in the range of 1

    摘要: A developing device (40) includes a developer bearer (45) to carry developer including toner and magnetic carrier to a developing range facing a latent image bearer (18); a casing (121) including a developer container (44; 47; 49) and an opening (51) to expose a part of the developer bearer (45); an opposing face (112A) of the casing (121) including a conductive material and opposing to a surface of the developer bearer (45) downstream from the developing range in a direction of rotation of the developer bearer (45); a developing bias source (141) to apply a developing bias to the developer bearer (45); and an insulation layer (123) disposed on the opposing face (112A) of the casing (121). The opposing face (112A) is disposed across, from the developer bearer (45), a casing gap (G1) sized to allow the developer borne on the developer bearer (45) to contact the opposing face (112A).
