Photothermographic material and method for forming images

A photothermographic material comprising:

• (a) a photosensitive silver halide,
• (b) a reducible silver salt,
• (c) a reducing compound represented by the formula (1) below,
• (d) a binder, and
• (e) a compound represented by the formula (2) below,
• wherein the amount of the compound represented by the formula (1) is 0.1–10 mole % of the amount of the compound represented by the formula (2), and
• an image can be formed by only a single sheet of the photothermographic material without a functional layer constituting a separate member;
• Q1—NHNH—R1 Formula (1):
• wherein Q1 represents a quinazoline ring bonding to NHNH—R1 at a carbon atom, and R1 represents a carbamoyl group of the formula —C(═O)—NH—R11 wherein R11 is an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 10 carbon atoms,
• wherein V1 to V8 each independently represent hydrogen atom or a substituent, and L represents a bridging group consisting of —CH(V9)— or —S— where V9 represents hydrogen atom or a substituent.
