The present invention deals with a flexible printed wiring board in the form of a printed wiring board wherein the conductive elements are fully encapsulated by an epoxy adhesive comprising a novel aromatic di-isoimide chemical compound. A stapler included in a finisher staples a stack of sheets each carrying image formed by the image forming section thereon. The complex oxide contains bismuth, sodium, barium, titanium, and copper. The respective linear electrode elements are arrange at equal intervals. The method can also include generating a filter from the set of one or more rules based off the measured one or more usage factors.
