To make image qualities of both faces uniform by constructing a recording medium in a nearly symmetric structure between the front and rear faces to carry out double-sided image printing.

At the time of rear face image printing, a separation hook 92 operates, and a medium Pa to be recorded is transferred to a transfer path for double-sided image printing 93 and stored in a tray 94. At this time, a image printing face faces downward. Thereafter, in the case of image printing to the other face (rear face), the medium to be recorded is transferred from the tray 94 to a transfer path for double-sided image printing 95. Since the preceding photoprinting face already faces downward, a image printing face of the rear face faces to each recording head at a image printing part. The medium Pa to be recorded has the structure in which the front and the rear are nearly symmetric to each other, and therefore the image qualities become equal between both faces. For making images of the front and rear faces agreed in the vertical relation, a rotation control mechanism for mechanically rotating the medium Pa in the tray 94 to be recorded by 180 degrees is set, or image data for the rear face is stored in a memory and a photoprinting control is executed to image print from the lower side of the rear face at the photoprinting part.
