In an image recording apparatus which does not generate ozone and has a simple structure, a pigment supply device where pigment is dispersed in liquid along with a surface active agent contacts with a layer of semiconductor of a photosensitive drum and the semiconductor layer is selectively exposed according to an image to be recorded by a light source. Then the pigment is attached onto the photosensitive drum, and then transferred and fixed onto an image recording paper as an output image. The surface active agent is oxidized by the light source and separated from the pigment to cause selected pigments from the pigment dispersed liquid to attach to the photosensitive drum.
