PURPOSE:To obtain the titled body having a high sensitivity and a less tendency for generating a fatigue due to repeated use by incorporating a specific hydrazone compd. to the titled body. CONSTITUTION:The hydrazone compd. shown by formula I is produced by effecting a condensation reaction of an aldehyde compd. shown by formula II and a hydrazine derivative or its salt shown by formula III in a solvent such as methanol, ethanol, dimethylformamide and dimethylsulfoxide, if necessary, in the presence of an acid or a basic salt. The titled body is constituted of a combination of a electrostatic charge transfer substance composed of the hydrazone compd. shown by formula I and a prescribed electric charge generating substance. The constitution of the titled body is examplified, for example, the conductive layer/the layer contg. the electric charge generating substance/the layer contg. the electrostatic charge transfer substrate, the conductive layer/the layer contg. the electric transfer substance/the layer contg. the electric charge generating layer, the conductive layer/the layer contg the electric charge generating substance and the electric charge transfer substances, the conductive layer/the layer contg. the electric charge generating substance/the layer contg. the electric charge generating substance and the electric charge transfer substance, etc. |
