A method of forming an image which comprises development processing an image-wise exposed silver halide photosensitive element in the presence of at least one compound represented by the following general formula (I): ##STR1## wherein X⊖ represents an anion; R 1 represents a --Y--R 3 group, a --Y--COOR 3 group, a --Y--OCOR 3 group, a --Y'--COO--Y--OCO--R 3 group, a --Y'--OCO--Y--COO--R 3 group or a --Y'--COO--Y--COO--R 3 group; Y represents an alkylene group having 1 to 18 carbon atoms, an arylene group or an aralkylene group; R 3 represents an alkyl group having 1 to 18 carbon atoms, an aryl group, an aralkyl group, a ##STR2## group or a ##STR3## group; R 4 represents an alkyl group having 1 to 18 carbon atoms, an aryl group or an aralkyl group; R 2 represents a hydrogen atom, a halogen atom, an alkyl group having 1 to 12 carbon atoms, an aryl group having 6 to 12 carbon atoms, an aralkyl group having 7 to 12 carbon atoms, an oxycarbonyl group (--COOR 5 wherein R 5 represents an alkyl group having 1 to 18 carbon atoms or an aryl group), an acyloxy group having 1 to 18 carbon atoms, an alkoxy group having 1 to 18 carbon atoms, an amino group, a substituted amino group, an acylamino group, a sulfonamido group, a carbamoyl group, a ##STR4## group or R 1 ; Y' is an alkylene group having 1 to 12 carbon atoms, an arylene group, an aralkylene group or a single bond; with the proviso that R 1 or R 2 contains at least one ester group. |
