An image-forming process involving a heating step is disclosed, which comprises conducting the heating in the presence of a compound represented by the following general formula (I): ##STR1## wherein: R.sup.1 and R.sup.2, which may be the same or different, each represents a group selected from an aryl group, a substituted aryl group, a heterocyclic group, and a substituted heterocyclic group;

Image-forming process involving heating step

A color light-sensitive material is disclosed. The material is comprised of a support having provided thereon at least one image-forming compound represented by formula (I) ##STR1## wherein X, Y, q, and Dye are as defined herein. The light-sensitive material shows excellent yellow dye-transferring properties and provides a yellow dye having excellent light fastness.

Color light-sensitive material

A color light-sensitive material is disclosed. The material is comprised of a support having provided thereon at least one image-forming compound represented by formula (I)

A method for forming an image, which comprises heating a light-sensitive material in the presence of a compound capable of forming a 2-mercaptobenzazole ring by a ring closing reaction when heated. In accordance with the method of the present invention, development is stopped at an appropriate time of development whereby an image having a high maximum density and low fog is obtained. A heat-developable light-sensitive material containing the compound is also disclosed.

Method for forming an image

A heat-developable photosensitive material comprising at lesat (1) a photosensitive silver halide, (2) a binder, (3) a dye-providing substance, and (4) a specific reducing agent other than commonly used reducing agents for silver halide on a support can be heat developed to produce images having a high density and less fog and has improved shelf stability.

Method for developing a heat-developable photosensitive material

A novel method for formation of an image comprising a heating step, comprising the heating carried out in the presence of a compound of general formula (I):

Method for formation of an image comprising a heating step

A process of forming images by heat developing a heat developable light-sensitive material after imagewise exposure is described, comprising heating a heat developable light-sensitive material in the presence of a compound represented by general formula (I) ##STR1##

Image forming process

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;

Image forming method including heating step

A heat developable color photographic light-sensitive material is described, comprising
