A gloss-imparting device for imparting a gloss on a color image, the gloss-imparting device has a transparent toner image-carrying body, a transparent toner image-forming unit, a heatingpressurizing unit, and a coolingreleasing unit. According to the present invention, the electric cable is prevented from running off from the drawer unit due to the folding of the cable caused by the regulating member, so that the electric cable is prevented from getting hung up on the parts disposed in the body. When the eye-optics are adjusted, this movement causes a movement in the linked reflectors that maintains a constant length for the optical path. The number particle size distribution value D90 of the expanded cell is not more than 50 times of the number particle size distribution value D10 of the toner. The penetrating member sensor is configured to provide information relative to a depth of penetration of a penetrating member through a skin surface.
