An image formation device has an image carrier and a development device (50) into which development units housing toner are detachably installed. The development units have storage device storing color and toner amount remaining information. And the image formation device operates in monochrome printing mode when development units of the same color are installed. The image formation device has display unit (95) to display the toner remaining amount in development units, and control unit which acquires color and toner amount remaining information in the storage device, and executes control to enable switching between a separate remaining amount display mode (95A,95C) to separately display on the display unit the toner amount remaining in each of installed development units corresponding to installation positions, and a total remaining amount display mode (95B,95D) to display on the display unit the total toner amount remaining in installed development units of the same color.
