PURPOSE:To obtain a clear image which does not occur falling off a fine line and abnormal discharging in high density recording, such as 400 dots/inch by incorporating a specific oily substance in a conductive body layer. CONSTITUTION:The oily substance contd. in the dielectrics layer of the titled body is a liquid at a normal temp., and has the volume resistivity of >=10<8>OMEGA.cm not to reduce the density of a recording image. The oily substance is preferably exemplified by a phthalic acid ester, a fatty acid dibasic ester, a fatty acid ester, an epoxy compd., a phosphoric acid ester and a polyester, and has preferably >=250 deg.C b.p., further preferably, >=300 deg.C b.p. The compounding amount of the oily substance is 0.1-20pts.wt., preferably, 1-10pts.wt., further preferably 2-6pts.wt. based on 100pts.wt. the solid matter of the dielectrics layer. Thus, the clear recording image which does not occur the falling off the fine line and the abnormal discharging, is obtd. even in case of the high density electrostatic recording such as 400 dots/inch. |
