  • Patent number: 5946523
    Abstract: A toner developing quantity detection unit operates a plurality of electrostatic recording units to transfer Y, M, C and K color component toner marks onto a belt. A toner developing quantity correction unit detects toner developing quantities per unit area of color toners on the basis of detection signals of the color component toner marks on the belt optically detected by a sensor. The toner developing quantity correction unit corrects the toner developing quantities so as to allow the toner consuming quantities of the plurality of electrostatic recording units to be substantially the same level, on the basis of the thus detected toner developing quantities.

  • Patent number: 4958002
    Abstract: High purity crystals of a biphenyltetracarboxylic dianhydride produced by dehydration of a biphenyltetracarboxylic acid, which contain almost no biphenyltricarboxylic acid or its anhydride, or a small amount such as an amount of not more than 0.2 wt. %, are of value to produce an aromatic polyamic acid or polyimide having an increased high molecular weight. The high purity crystals of a biphenyltetracarboxylic dianhydride can be prepared from a biphenyltetracarboxylic acid by a dehydration process wherein the biphenyltetracarboxylic acid is heated under carefully controlled conditions.
