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.

摘要： The toner for electrostatic image development has excellent charge properties, by which excellent toner particle size-controlling ability is achieved, and moreover the sharpening of a particle size distribution is achieved. The toner is composed of toner particles containing a binder resin. The process has an aggregating step of adding an aggregating agent containing a transition element into an aqueous medium of dispersed fine binder resin particles to aggregate the fine binder resin particles, and an aggregation-stopping step of adding an aggregation stopper composed on a sulfur atom-containing compound exhibiting a reducing action on the aggregating agent. The aggregating agent is a salt of a bivalent or higher metal selected from Sr, Ti, V, Cr, Mn, Fe, Co, Ni and Cu.
