PROBLEM TO BE SOLVED: To provide a photograph printing device constituted so that average light quantity per unit area on a photographic paper can be made constant and the irregularity of the light quantity caused in a light irradiation area on the photographic paper can be suppressed when a printing action is executed by switching plural printing lenses. SOLUTION: The plural printing lenses 3A, 3B and 3C are selectively arranged on the optical axis of light emitted toward the photographic paper 6 from a DMD 2. Besides, plural ND filters 4A, 4B and 4C corresponding to the respective printing lenses are selectively arranged on the optical axis of light emitted to the DMD 2 from a light source 1. The filters 4A, 4B and 4C are processed so that the transmitted light quantity thereof becomes different at the central parts and the peripheral parts thereof. Besides, the transmitted light quantity is set so that the average light quantity per unit area on the paper 6 is made constant even when any printing lense is selected.
