Abstract

PURPOSE:To obtain a flexible receptor having high photosensitivity and giving a clear image by forming a photosensitive layer contg. a specified hydrazone compound on an electrically conductive support. CONSTITUTION:On electrically conductive support 1 photosensitive layer 2 is formed contg. a hydrazone compound as a photoconductive substance represented by the formula (where R is H, alkyl, alkoxy or dialkylamino and n is 1-3) together with a sensitizing dye absorbing light in the visible region to increase the sensitivity in the visible light region. Thus, a receptor is manufactured. Photosensitive layer 2' contg. charge carrier generating substance 3 besides the hydrazone compound may be formed, or the forming charge carrier generating layer 5 contg. substance 3 and charge transferring layer 6 contg. the hydrazone compound on support 1 in order, composite photosensitive layer 2'' may be formed. This receptor has high photosensitivity and gives a clear image whether charged positively or negatively.
