Abstract

A heat-developable light-sensitive material comprising a support having therein or in one or more layers thereon an organic silver (b) a light-sensitive silver halide, and (c) a reducing agent, with the light-sensitive silver halide comprising the reaction product of a part of the organic silver salt and an N-halo compound represented by the following formula (I): ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each is a hydrogen atom; an alkyl group having 1 to 22 carbon atoms; a haloalkyl group having 1 to 22 carbon atoms; an amino group; a hydroxyalkyl group having 1 to 22 carbon atoms; an allyl group; a naphthyl group; a benzyl group; a ##STR2## group in which R.sub.5 is a hydrogen atom, a halogen atom, an alkyl group, an alkylthio group, an amino group or an alkylamino group; a benzyloxy group; an aryl group; a haloaryl group; an alkylaryl group; and alkoxyaryl group; an --OR.sub.6 group in which R.sub.6 is a hydrogen atom, an alkyl group, an allyl group, an aryl group or an alkoxyaryl group; a ##STR3## group in which R.sub.7 and R.sub.8 each is a hydrogen atom, an alkyl group, an aryl group or an allyl group; a cyclohexyl group; a --CH.sub.2 OR.sub.9 group in which R.s…
