To provide a photosensitive lithographic printing plate material suitable for exposure with laser light having an emission wavelength of 350-450 nm, and having high sensitivity and excellent storage stability.

The photosensitive lithographic printing plate material has a photosensitive layer containing a photopolymerization initiator, a polymerizable compound and a polymer binder on a support, wherein the photosensitive layer contains a compound represented by general formula (I) as the photopolymerization initiator. In the formula, R1-R8 each represent H or a substituent, adjacent groups may bond to each other to form a ring; R9 represents a divalent linking group which may have a substituent; and R10 represents an alkyl, aryl, heteroaryl or alkenyl group which may have a substituent.
