Abstract: Disclosed is a stabilized enzyme composition for use in clinical examination, comprising: (a) an enzyme component comprising at least two enzymes selected from the group consisting of alkaline phosphatase, creatine kinase and alanine aminotransferase; (b) a stabilizer component comprising effective stabilizing amounts of an albumin, and at least one saccharide selected from the group consisting of trehalose and sorbitol; and (c) an aqueous medium having dissolved therein the components (a) and (b). The enzyme composition of the present invention is stable for a prolonged period of time not only under non-freeze refrigeration conditions, but also under freezing conditions or under conditions for non-freeze refrigeration after thawing of the frozen composition, as compared to the conventional enzymatic compositions.

Abstract: An image forming apparatus includes a photosensitive unit and a developing unit, at least one of which is arranged rotatable about a parallel support shaft. In a state that the both units are mounted on an apparatus main body, a developing roller gear (driven gear) of the developing unit is in mesh with a drive gear provided on the photosensitive unit. A drive force is transmitted from the drive gear to the developing roller gear. The developing roller gear and the drive gear are arranged such that a drive force acting on a pitch point has an extension line passing through a center of the parallel support shaft.
