An image forming device is disclosed, and includes a photosensitive drum,
a laser unit for irradiating the photosensitive drum with laser light,
developing units for developing the electrostatic latent image on the
surface of the photosensitive drum, a toner container for containing
toner to be supplied to the developing device, and toner supply pipes
located so as to be movable between a supply position for supplying the
developing units with the toner in the toner container, and a retracted
position apart from the developing units. The toner supply pipes are
located in a laser light path of the laser unit in the supply position,
and are located so as to allow the laser light from the laser unit to
reach the photosensitive drum in the retracted position.
