PURPOSE:To always maintain formation of high-quality images by incorporating a specified compound in a photosensitive layer. CONSTITUTION:The photosensitive layer contains the compounds represented by formula I and II in which each of X1 and X2 is trimethylmethyl, or dimethylethylmethyl, and each of R1, R2, X3 and X4 is H, 1-10C alkyl, or 2-10C alkenyl. They are used in total in an amount of 0.5-20wt.%, preferably, 2-15wt.% of the total weight of the photosensitive layer, and in a mixing ratio of 0.1:1-1:0.1, preferably, 0.3:1-1:0.3, thus permitting potential stability under an environment of corona discharge to be enhanced and always stable high-quality images to be formed. |
