A magenta toner for electrophotography, including: toner particles containing, a polyester resin, a coloring agent containing a solid solution of C. The 16 VCSELs disposed in the light-emitting device emit optical signals in the same direction. The first surface of the semiconductor chip is electrically coupled to an intermediate substrate via conductive bumps. The lifting element is disposed at a right angle to the conveying direction and is displaceable below a support surface of the conveying device. The pad can be translucent or transparent. In use the body is attachable intravertebrally to each of the first and second bony portions to distract each of the first and second bony portions while allowing motion between each of the first and second bony portions.
