摘要： A fixing belt is applied to a fixing apparatus of an electronic photography type printer. The fixing belt consists of a belt base and an elastic layer having a thickness of 200 .mu.m or more formed on the belt base. The elastic layer consists of first, second and third elastic layers arranged in that order from the base side, and is deformable to conform to the surface shape of a recording paper so that all unfixed toner held on the recording paper can be pressed. The second elastic layer is a barrier layer for preventing releasing agent from permeating and the belt from swelling to suppress the thickening of the elastic layer as a whole and maintain the belt thickness within a range that does not cause any image noises.

摘要： A fixing apparatus for controlling an oil transfer apparatus to maintain a releasing agent holding layer such that it is not always saturated with the releasing agent. This makes it a compact, cost-effective unit with a long service life and provides a uniform, stable oil coating that eliminates image noise problems. In order to use a constant and minimum necessary amount of releasing agent, a releasing agent supply nozzle is incorporated with multiple protrusive or retrusive droplet growth assisting members at or near multiple releasing agent discharge ports. The supply nozzle used for supplying the oil has multiple discharge holes having approximately equal opening cross-sectional areas and an equalizing member which equalizes the amount of oil discharged from each discharge hole. The outer diameter D1 of the oil supply roller, the outer diameter D2 of the metal core and the distance P of adjacent through-holes formed on the periphery of the metal core satisfy a relation, 0.6

摘要： A finisher is disclosed which is connected to a copying machine and possessed of a stapler which effects a stapling treatment on the sheets discharged from the copying machine and a binder which inserts the discharged sheets into a cover and binds by adhesion the sheets and the cover for bookbinding. This finisher has a memory for memorizing the stapling treatment or the binding treatment as a treating mode in advance, a staple sensor for detecting the existence of the staple, and a cover sensor for detecting the existence of the cover. When either of the sensors detects the lack of staple or cover, a feasible treating mode other than the unfeasible treating mode due to the lack of staple or cover in the treating mode memorized in the memory is executed prior to the unfeasible treating mode.
