    摘要: A carrier for use in developing an electrostatic or magnetic latent image in electrophotography, electrostatic recording, electrostatic printing or the like, which carrier is produced by atomizing a molten mixture of a magnetic powder and a binder resin containing a polyolefin and a polyolefin having a functional group. The polyolefin having a functional group is present in an amount ranging from about 50% by weight or less based on the total weight of the binder resin.

    摘要: The present invention relates to an inorganic antibacterial agent comprising a thermoplastic resin and inorganic antibacterial particles dispersed in the resin, and a shape factor SF2 defined by the following formula: SF2=100πL2/(4A) (Wherein L represents a perimeter of a plane image of a particle which is obtained from observation of a slice for inorganic antibacterial agent using a transmission electron microscope, and A represents the area of the plane image.) is not more than 200, and the existing ratio defined by the following formula: Existing ratio (%)=100×(number of inorganic antibacterial particles having SF2 of not more than 200)/(number of particles used for calculation of SF2) is not less than 80%. According to the present invention, when the inorganic antibacterial agent is dispersed in the antibacterial molded resin product, the dispersion of inorganic antibacterial agent is improved since inorganic antibacterial particles are dispersed in the thermoplastic resin. Moreover, inorganic antibacterial particles are dispersed homogeneously in the base resin since the occurrence of agglomeration and localization are well prevented in the thermoplastic resin.

    摘要: A process for producing a developer carrier is disclosed, which comprises heating a carrier composition containing a resin, magnetic particles and a compound having a lower critical surface energy than the resin, to produce a carrier particle having a higher surface concentration of the compound having a lower critical surface energy. A developer carrier having an average particle size of at least about 50 .mu.m and containing a fluorine-containing compound and fine magnetic particles dispersed in a binder resin is also disclosed. The developer carriers according to the invention when used in magnetic brush development provide superior charge generation, extended life and improved image reproduction.
