Title: Developing method for electrostatic latent image
Inventor: KANEKO TADASHI
IPC: G03G15/08
Filed: 1986-08-06
Abstract: PURPOSE:To enable formation of a sharp image having excellent resolution and tone reproductions by forming a developer layer to be formed on a developer conveying body as a thin layer and using a resin coated carrier formed by coating a resin contg. a fluoroplastic on magnetic material particles as a carrier. CONSTITUTION:The developer layer to be formed on the developer conveying body is formed as the thin layer and the resin coated carrier formed by coating the rein contg. at least >=30wt% fluoroplastic on the magnetic material particles is used as the carrier. More specifically, the fluoroplastic has the characteristic of small critical surface tension; therefore, the carrier provides the smooth surface condition and the possibility of generating the 'toner-filming' to retard the frictional charge characteristic of the carrier by sticking of the toner material; for example, coloring material such as carbon black or release agent or the like to the carrier surface is decreased in the frictional charge of the carrier and the toner. The frictional charge of the polarity and charge quantity adequate for the toner is thus stably imparted to the toner. The generation of the weakly charged toner is thereby considerably decreased and the carrier and toner are stably held on the developer conveying body. The good image is thus formed without generating the fogging.

Filed: 1986-08-06
Abstract: PURPOSE:To produce a low iron loss grain oriented electrical steel sheet with which the effect of decreasing the iron loss is not lost even if the steel sheet is subjected to a heat treatment such as stress relief annealing by heating the grain oriented electrical steel sheet subjected to finish annealing to an adequate temp. and imparting local plastic strain to the surface thereof in this state. CONSTITUTION:The grain oriented electrical steel sheet subjected to the finish annealing is kept heated at >=500 deg.C in; for example, the soaking zone of a continuous annealing furnace and is passed in this state between a roll having many knife edges extending along the axial direction on the surface of a cylindrical barrel and a flat roll, by which the linear plastic distortions in the rolling strain in the direction perpendicular to the rolling direction is locally imparted to the above-mentioned steel sheet. A high-dislocation density region is thereby formed linearly to the steel sheet and the iron loss is decreased by the segmentation of the magnetic domain width. The segmentation of the magnetic domain width is by the local plastic strain and the effect of decreasing the iron loss is not lost in spite of the subsequent heat treatment of high temp. such as stress relief annealing.
