Abstract

PURPOSE:To obtain superior image density by incorporating spacers of at least one of Al and Mg hydroxides having 5-15mum diameter and a pigment having a specified specific resistance into a dielectric layer. CONSTITUTION:This electrostatic recording body has a dielectric layer contg. spacers of at least one of Al and Mg hydroxides having 5-15mum diameter so that the spacers become projections by which the gap d1 between a multi- stylus electrode head 1 and the dielectric layer is kept uniform. In this case, the spacers having 5-15mum diameter are separate particles 2 of Al or Mg hydroxide or may be coagulated bodies 3 of hydroxide particles. The dielectric layer further contains a pigment having >=10<6>OMEGA.cm specific resistance as an index of insulation. The pigment may be a pigment surface-treated with alumina or calcium pyrophosphate. Polyvinyl acetate may be used as a resin forming the dielectric layer. The insulating property can be improved and superior recording density is obtd.
