    • This invention relates to a composite function element which includes a high resistance thin film layer containing the constitutional elements of a perovskite type oxide and specified impurity elements at the grain boundary of a sintered body, said sintered body comprises an agglomerate of n type semiconductor particles and to a process for producing said composite function element. The composite function element has a composite function such that it acts as a varistor passing high voltages at a high voltage and as a capacitor passing the currents of abnormal frequency zone at a low voltage, so that the functions of two elements, a varistor and a capacitor, can be fulfilled simultaneously with only one element. Therefore, its extensive application in uses such as, for example, prevention of erroneous operation of microcomputer-controlled instruments can be expected.

    • An exhaust mechanism for use in an image development apparatus exhausts air from within the apparatus, taking advantage of an air flow generated by the heating of a fixing unit without the need for an air blower. The apparatus includes a transport path for allowing a recording medium, to which a toner image formed on a photoconductive body, is transferred, to pass therethrough, a transfer unit disposed below the photoconductive body for transferring the toner image to the recording medium, the fixing unit having a heater, and a partitioning plate which separates a space formed below the transfer unit from a space that accommodates the photoconductive body, a toner image forming unit, and the fixing unit, and which is provided with an opening for permitting air to flow near the transfer unit. With this arrangement, a ventilation path for exhausting air outwardly from within the apparatus is formed without the need for the air blower, in which a rising air flow is exhausted, passing through the opening in the partitioning plate, near the transfer unit, and through an opening formed in the cabinet of the body of the apparatus.
