Provided is a charging roll for electrophotographic equipment with which any increase in resistance and any bleeding of ionic electroconductive agent while energization persists can be minimized. A charging roll 10 for electrophotographic equipment, the charging roll 10 comprising a shaft body 12 and an elastic layer 14 that is formed on the outer peripheral surface of the shaft body 12, the elastic layer 14 being a crosslinked article of a rubber composition containing the following components (a) to (e). (a) One or more selected from hydrin rubber and nitrile rubber, (b) a crosslinking agent, (c) an ionic electroconductive agent, (d) one or more selected from piperidinyloxy radical compounds and phenolic antioxidants, and (e) one or more selected from salts of cyclic amidine compounds and thiophthalimide compounds.

The present disclosure generally relates to optical molecules, including but not limited to 1,3-thiazolidin-4-ones and other molecules comprising an aza-heterocyclic ring system containing a chalcogen. In some embodiments, the molecules may absorb light between 300 nm and 800 nm, e.g., appearing as various colors, depending on the absorbance. In some cases, the optical molecules can be used as color additives, pigments, dyes, or the like. Other embodiments of the disclosure are generally directed to systems and devices using such compounds, methods of using such compounds, kits involving such compounds, or the like.
