摘要： A monomer to produce polybenzimidazole is dissolved in polyphosphoric acid. For example, polysulfated phenylene sulfonic acid (acidic group-possessing polymer) is further dissolved in this solution. In this procedure, the acidic group-possessing polymer and the monomer are adsorbed to one another in accordance with the acid-base interaction. When the monomer is polymerized, for example, by means of dehydration polymerization in this state, then polybenzimidazole is synthesized, and the polybenzimidazole and the acidic group-possessing polymer are compatibilized with each other to produce a compatibilized polymer. When the compatibilized polymer is deposited as a solid, and the solid is separated from polyphosphoric acid, then the compatibilized polymer is obtained. A proton conductive solid polymer electrolyte as a final product is manufactured by forming the compatibilized polymer to have a predetermined shape.

摘要： This invention relates to an image forming apparatus which forms an image on a transfer medium using a two-component developing agent by electrophotography. An image forming apparatus according to this invention includes a potential sensor which measures the charging potential on an image forming body and a patch density sensor which detects the toner attraction amount of a patch image. In the image forming apparatus, a toner charge amount Qt (&mgr;C/g) is calculated from the potential of a patch image before and after development detected by the potential sensor and the image density of a developed patch image detected by the patch density sensor, and image formation is performed by setting image formation conditions based on the calculated toner charge amount Qt. To set the image formation conditions, a table which stores in advance an image formation condition corresponding to the toner charge amount Qt is used.
