5 n7 A photographic printing apparatus includes conveying rollers (38) for conveying a film (36) on which images are recorded, an image sensor (76) for measuring image density, a device (28) for determining printing conditions based on a measured image density and for storing the printing conditions, a display (78) for simulating an image to be printed onto photographic printing paper (54) based on results of measurement by the image sensor (76) and for displaying a simulated image, a reflecting mirror (70), and a control device (28). The reflecting mirror (70) is movable between a first position, at which the reflecting mirror (70) guides light, which is irradiated from a light source (12) and which passes through the film (36) at a printing position, to the image sensor (76), and a second position, at which the reflecting mirror (70) guides light, which passes through the film (36), to the photographic printing paper (54). The control device (28) controls the conveying rollers (38), the image sensor (76), the device for storing (28), and the reflecting mirror (70) so that when the reflecting mirror (70) is at the first position, for each frame, a density of an image at the printing position is measured and printing conditions of the image are determined based on the results of measurement and are stored, and thereafter, the reflecting mirror (70) is moved to the second position and, for each frame, an image at the printing position is printed onto the photographic printing paper (54) under stored printing conditions.
