摘要： An objective is to provide a carrier exhibiting stable charge providing ability in which sufficient charge can be provided to toner having a small particle diameter, and no image contamination such as fog caused by toner scattering via lack of electrification is generated. Another objective is to provide a carrier capable of maintaining a charging level of no interference for image formation even under the image forming condition at which a charging level for printing a number of prints continuously is difficult to be maintained. Disclosed is a carrier comprising a core particle made of ferrite possessing Mg and coated thereon, a resin, wherein the core particle has a ratio of the number of irregular-shaped core particles of at most 5%, based on the total number of core particles, and a surface of the core particle has grains having a maximum grain diameter of 2-5 μm.

摘要： The non-contact information recording medium is made by forming the antenna circuit and connecting it to the IC module through connection terminals at the same time. This provides a high degree of freedom of patterning of the antenna circuit. The antenna circuit is formed on a recording substrate, in which an IC module has been embedded. A foil-bonding resin layer is formed on the connection terminals of the recording substrate, with a toner containing a binder resin by an electrophotographic method. Then a conductive foil is brought into contact with the foil-bonding resin layer to bond the foil to the resin layer, to connect the antenna circuit to the connection terminals and form the antenna circuit composed of the conductive foil.
