PROBLEM TO BE SOLVED: To provide occurrence of pressure fog when stored at high temperature by incorporating a specified compound and a specified coupler in at least one of photosensitive layers. SOLUTION: At least one of the photosensitive layers contains a compound selected from formula I and the like, and the acyl-acetoamide type coupler selected from formula II and/or a coupler selected from formula III and the like, and in formulae I-III, Ra1 is an alkyl, alkenyl, aryl, or acyl group or the like; Ra2 is an H atom or a group same as Ra1 ; R1 is a substituent; Q is a nonmetallic atomic group necessary to form a 3-∼5-membered hydrocarbon ring or a 3-∼6-membered ring having hetero atoms, such as N or O, together with the C atom; each of X1 and X2 is an alkyl or aryl or heterocyclic group: Y is an aryl or a heterocyclic group; and Z is a group to be released by reaction of the coupler of formula III with the oxidation product of a developing agent.
