    Abstract: A toner for developing an electrostatic latent image, wherein in regard to the molecular weight by GPC of the THF dissolved components of the toner, the ratio of at least 5×105 in the integral molecular weight distribution is not higher than 1% by weight, the ratio of not higher than 3×103 is not higher than 30% by weight, and the ratio {W(5×103)/W(1×105)} of the ratio {W(5×103)} of not higher than 5×103 to the ratio {W(1×105)} of at least 1×105 is from 15 to 50. Also, the molecular weight by GPC of the THF dissolved components of the toner is distributed in the range of not larger than 1×106, the value of the differential molecular weight distribution of the molecular weight of 5×103 is not larger than 0.55%, and the value of the differential molecular weight distribution of the molecular weight of 1×105 is not larger than 0.15%.

    Abstract: An optical element which exhibits a great improvement in durability even after repeated use. The optical element comprising a substrate having thereon (a) a recording layer comprising a liquid crystal polymer composition and (b) a surface protective layer in this order, in which the protective layer comprises a plurality of layers laminated such that the hardness thereof increases from the layer adjacent to the recording layer toward the uppermost layer in order, or the protective layer comprises a plurality of layers laminated such that the glass transition point thereof becomes higher from the layer adjacent to the recording layer toward the uppermost layer in order. Furthermore, the layer adjacent to the recording layer preferably has a pencil hardness of HB or higher and the uppermost layer preferably has a pencil hardness of 3 H or higher.
