To provide a high contrast heat developable recording material less liable to cause unevenness in an image and ensuring suppressed fog in heat development and having superior sensitivity and high maximum density.

In the heat developable recording material having a recording layer containing a non-photosensitive organic silver salt, photosensitive silver halide and a reducing agent which acts under heat on a support, a contrast enhancer of formula (1) or (2) and a silane compound of the formula (R1 O)mSi-(L1-R2)n (7) or formula (8) are contained in the recording layer or at least one of layers adjacent to the recording layer.
