Disclosed is a green toner for developing a static latent image containing a binder resin and a colorant, and the colorant contains C. Also, a lighting device comprising at least one solid state light emitter and at least one luminescent element spaced from the light emitter, a surface of the luminescent element surface being at least twice as large as and substantially parallel to the illumination surface of the light emitter. The electrically insulative material comprises at least one of SixOyNz and AlpOq, wherein p, q, x, y and z are greater than 0 and less than 10. In this embodiment, the subject apparatus can use these components as the means for lifting the subsided slab.
