A method for forming an image which has a step of heating an image-forming material in the presence of a compound represented by formula (I), whereby unevenness of image density and increase in fog due to fluctuation of development temperature, which have so far been caused in heat-developable photosensitive materials, can be prevented from occurring: ##STR1## wherein R represents a hydrogen atom, or a group selected from a class consisting of groups represented by formulae (A) to (C) ##STR2## wherein R.sup.11 and R.sup.12 each represents a substituted or unsubstituted alkyl group, a cycloalkyl group, a substituted or unsubstituted alkenyl group, an aralkyl group, a substituted or unsubstituted aryl group, a heterocyclic group, an alkyloxy group, an aryloxy group, an alkylthio group, an arylthio group, or a substituted or unsubstituted amino group, or R.sup.11 and R.sup.12 combine with each other to form a 5- or 6-membered ring; Q represents a hydrogen atom, an alkyl group, or an aryl group; TIME represents a timing group; PUG represents a photographically useful agent moiety; n represents 0 or an integer; and Z represents atoms forming a benzene ring.
一种形成图像的方法,其中包括在式(I)所表示的化合物存在下加热图像形成材料的步骤,从而可以防止在热显影光敏材料中由于显影温度波动而引起的图像密度不均和雾化增加:##STR1## 其中R表示氢原子或者从式(A)到式(C)所表示的群组中选择的群组,##STR2## 其中R.sup.11和R.sup.12分别表示取代或未取代的烷基,环烷基,取代或未取代的烯基,芳基烷基,取代或未取代的芳基,杂环基,烷氧基,芳氧基,烷硫基,芳硫基,或取代或未取代的氨基,或者R.sup.11和R.sup.12结合起来形成一个5-或6-成员环;Q表示氢原子,烷基或芳基;TIME表示计时群;PUG表示具有摄影用途的代理分子;n表示0或整数;Z表示形成苯环的原子。
