An image recording apparatus uses coloring photosensitive toner for a full-color copying which is in the form of a microcapsule having a shell, a photosensitive resin and a chromogenic material both encapsulated in the shell, and a developer material coated on the outer surface of the shell. To increase the monochromatic copying speed, the apparatus further uses a monochromatic toner. When a user's switch is depressed, a driver unit selects either one of the full-color and monochromatic color copying mode. When the monochromatic image is to be copied, a pressure developing unit which is used for pressure developing a color latent image is retracted, so that a recording medium on which a monochromatic toner image is deposited is free from the pressure imparted by the pressure developing unit and the pressure developing unit is not smeared with the monochromatic toner powders.
