    Abstract: An image forming apparatus includes a latent image bearer to rotate, an image forming unit including a charger and a developing device, a charge power supply to output a charging bias applied to a charger, a transfer device, a toner adhesion amount, and a controller. The controller causes the image forming unit to form a background fog pattern in a background area of the latent image bearer while changing a background potential, acquires toner adhesion amount values detected at different positions of the background fog pattern, having different potentials, sorts the toner adhesion amount values in an order of the background potential, determines a relation between the background potential and background fog amount based the toner adhesion amount values except any toner adhesion amount value out of monotonicity, and adjust the charging bias to an optimum value computed based on the determined relation.

  • Patent number: 8092720
    Abstract: Polymer supported metal complex catalysts and methods of their preparation and use are described. The polymer supported metal complex catalysts can be obtained via ligand exchange reactions between polymer ligands and a metal complex having catalytic activity. For example, a polymer supported rhodium (II) complex catalyst can be prepared via ligand exchange reaction between an insoluble polymer and a rhodium (II) carboxylate complex, wherein the insoluble polymer is prepared by a copolymerization reaction of (i) a styrene derivative with a substituted carboxylic acid, (ii) a styrene, and (iii) a linear alkane with both ends substituted by vinylbenzyloxy groups. The polymer supported catalysts can be used to catalyze asymmetric carbene reactions such as C—H insertion reactions and the like with high catalytic activity, chemical selectivity, diastereoselectivity, and enantioselectivity.
