Abstract
An image printer includes a transport device for transporting standard and auxiliary photosensitive materials to a developing unit, an exposure system for exposing the photosensitive materials. The transport device includes a standard transport unit and an auxiliary transport unit. The standard transport means transports to the developing unit the standard photosensitive material having sensitivity to a wavelength range of the three primary color components of light. The auxiliary transport unit transports to the developing unit the auxiliary photosensitive material having sensitivity to a light wavelength range different from that of the standard photosensitive material. The exposure system includes a standard exposure unit and an auxiliary exposure unit. The standard exposure unit exposes the standard photosensitive material at an exposing position of the standard transport unit, while the auxiliary exposure unit exposes the auxiliary photosensitive material at an exposing position of the auxiliary transport unit.
