Abstract: When a photoreceptor unit and a developing unit are combined with each other, the photoreceptor does not come into direct contact with the developing unit. Accordingly, it is possible to prevent generation of scratches on the surface of photoreceptor, and lowering of electrostatic sensitivity due to scratches may be prevented. As a result, an excellent image will be formed. It improves the efficiency in the manufacture of image forming apparatus. A method of manufacturing an image forming apparatus of the present invention includes a process of applying a toner to the surface of developing roller and a process of making the developing roller with the toner applied thereto come into contact with the photoreceptor to combine the developing unit and the photoreceptor unit with each other. Preferably, the manufacturing method further includes a process of performing functional tests of a finished image forming apparatus.

Abstract: A printing apparatus includes a facsimile data receiving unit for receiving a reception request signal and print data which are transmitted through a telephone line; a computer data receiving unit for receiving print data transmitted through a line different from a telephone line; a printing unit for printing each of the print data received by the facsimile data receiving unit and the computer data receiving unit on a medium; and a mode setting unit for selectively setting a first mode in which, when the facsimile data receiving unit receives the reception request signal and the printing unit is printing the print data received by the computer data receiving unit, the printing process of the computer data is interrupted thereby allowing the printing unit to execute a printing operation of the print data from the facsimile data receiving unit in accordance with the reception request signal, and a second mode in which when the facsimile data receiving unit receives the reception request signal and the printing
