PURPOSE:To prevent generation of dot failure or abnormal dot in a high density recording without requiring electrification treatment on an electrostatic recording body prior to recording by incorporating a specified kaolin as a spacer into a dielectric body. CONSTITUTION:Generation of dot failure or abnormal dot in a high density recording is prevented without subjecting an electrostatic recording body prior to recording to electrification treatment. Kaolin 2 contg. <=2wt.% quartz of 5-15mu equivalent diameter is incorporated as spacer into a dielectric body layer. Thus, kaolin 2 is contained as pigment having a function for keeping a distance d1 between a multiprobe electrode head 1 and a dielectric body layer of the electrostatic recording body at a fixed value. By this constitution, a distinct picture image contg. no dot failure nor abnormal dot, nor unevenness of recorded density is obtd. in a high density electrostatic recording without requiring a stage for giving previously a static charge of reverse polarity to the static charge for recording. |
