A method of forming a photographic image which comprises development processing with an alkaline activator solution a silver halide photographic light-sensitive material comprising a support having thereon at least one surface latent image type silver halide emulsion layer, and containing in at least one layer selected from the silver halide emulsion layer and another hydrophilic colloid layer (1) a developing agents; (2) an acylhydrazine compound represented by formula (I): R.sup.1 NHNHCOR.sup.2 (I) wherein R.sup.1 represents an unsubstituted or substituted aryl group or alkyl group; and R.sup.2 represents a hydrogen atom, or an unsubstituted or substituted aryl group or alkyl group; and (3) at least one compound represented by formula (II): ##STR1## wherein each of W.sup.1 and W.sup.2 can represent a hydrogen atom or an aliphatic group or W.sup.1 and W.sup.2 are bonded each other to form a ring; W.sup.3 represents a divalent aliphatic group; Q.sup.1 represents a simple bond or a divalent heterocyclic group containing a nitrogen atom, an oxygen atom, or a sulfur atom; and M represents a hydrogen atom, an alkali metal atom, an alkaline earth metal atom, a quarternary ammonium salt, a quarternary phosphonium salt, or an amidino group, or an inorganic acid salt or an organic acid salt thereof. According to the activator type developing method, a dot image having good dot quality and screen range can be obtained.
一种形成照片图像的方法,包括使用碱性激活剂溶液对含有银卤化物的光敏感银盐照片材料进行显影处理,该材料包括支撑物,其上至少有一个表面潜影像型银卤化物乳液层,并且在所选的至少一层中含有以下物质:(1) 显影剂;(2) 由式(I)表示的酰肼化合物:R.sup.1 NHNHCOR.sup.2 (I),其中R.sup.1表示未取代或取代的芳基或烷基;R.sup.2表示氢原子,或未取代或取代的芳基或烷基;以及(3) 由式(II)表示的至少一种化合物:##STR1## 其中W.sup.1和W.sup.2中的每一个都可以表示氢原子或脂肪基,或者W.sup.1和W.sup.2彼此相连形成环;W.sup.3表示二价脂肪基;Q.sup.1表示简单键或含有氮、氧或硫原子的二价杂环基团;M表示氢原子、碱金属原子、碱土金属原子、季铵盐、季膦盐、或氨基甲酸基团,或其无机酸盐或有机酸盐。根据激活剂型显影方法,可以获得具有良好点质和屏幕范围的点状图像。
