    摘要： There is disclosed a positive charging type electrophotographic toner comprising a fixing resin, and a colorant and an electric charge controlling material, which are contained in the fixing resin, the electric charge controlling material being an electric charge controlling resin comprising a polymer which is compatible with the fixing resin, a molecular-weight distribution of the polymer resembling a molecular-weight distribution of a weight-average molecular weight of not more than 20,000 in the molecular-weight distribution of the fixing resin, and a group corresponding to a quaternary ammonium salt being contained at the side chain of the polymer. This toner is superior in charging properties, fixing properties, offset resistance and strength, because a resin having a quaternary ammonium salt group is used as the electric charge controlling material.

    摘要： The present invention provides a toner 1 for non-magnetic one-components developments to be used for a method for non-magnetic one-component contact type development, wherein an apparent density is not less than 0.32 g/cc and when supplying to a developing roller 2 immediately after the consumption at the black solid part, a charged amount is not less than 7 .mu.C/g at an absolute value. This toner is suitable for using in combination with an organic photoconductor and can prevent that a residual image of the black solid part is remained at the half tone part immediately after the development of the black solid part.

    摘要： A developing apparatus has a developer supporting member 41 with a surface roughness RZ in the range from 3.0 to 5.5 &mgr;m and a one-component developer T with a bulk density in the range from 0.35 to 0.55 g/ml, and an image is developed by forming a layer of the developer T on the developer supporting member 41. This makes it possible to form a thin toner layer stably despite changes in ambient conditions, and to prevent low image density and fogging. The absolute value of the amount of electric charge with which the developer T is charged is preferably in the range from 3.0 to 10.0 &mgr;C/g. The developer supporting member 41 is made preferably of stainless steel.

    摘要： In a positively chargeable toner, calcium carbonate fine particles having a certain average primary particle diameter are attached to the surface of toner base particles. The toner base particles contain at least a binder resin and a colorant. The calcium carbonate fine particles are ones which had been subjected to a surface treatment with a positively chargeable surface treating agent and a silicone oil. A mass ratio of the positively chargeable surface treating agent to the silicone oil attached to the surface of the calcium carbonate fine particles is set to be 7:3 to 3:7 in terms of the positively chargeable surface treating agent:the silicone oil.
