SOLUTION: A compound represented by the formula (in the formula, R represents alkyl, alkenyl, alkoxy or alkenyl oxy, (n) represents an integer of 1-5, and R can be same or different when (n) is 2 or more.) is contained in an image forming layer. The compound represented by the formula is synthesized by benzoic acid, substituted by R, benzoate, aminobenzene and the like, or prepared by reacting hydroxybenzamide with an alkyl halide or alkenyl halide. The addition amount of the compound represented by the formula is 0.1-20wt.%, preferably 0.5-12wt.%, in the image forming layer. |
