PROBLEM TO BE SOLVED: To make improvements in sensitivity by including for formation an image forming layer containing a second reducer containing a support and an oxidant, a first reducer, and a boron compound having at least one boron- hydrogen combination. SOLUTION: The thermography image forming element is formed by including an image forming layer containing (a) support and (b) (i) an oxidant, (ii) a first reducer, and (iii) at least one boron-hydrogen combination. The oxidant is preferable to be a silver salt of organic acid. The first reducer can be selected from various kinds of reducers (also, known as a developing main agent or developer) known in the technical field in the use of a thermography image forming element. The boron compound useful as a second reducer has at least one boron-hydrogen combination. Also, the thermography image forming element can contain another additive for assisting formation of useful images. |
