PROBLEM TO BE SOLVED: To easily eliminate paper powder or toner accumulated at the recessed parts of the housing of a printing device existing at the left and the right parts of a toner cartridge and to reduce the number of parts of the whole device by providing the printing device with a pair of covers which covers the recessed parts of the housing of the device and which is provided with bearing parts bearing the shaft of a photoreceptor. SOLUTION: The printing device 6 is provided with a pair of covers 1-a which covers the recessed parts 4 of the housing of the printing device 6 existing at the left and the right parts of the toner cartridge 7 and which is provided with the bearing parts 2 bearing the shaft of the photoreceptor drum 8 and hole parts 10-a in which the fitting legs of the covers 1-a are inserted. The covers 1-a are provided with flat surfaces receiving dirt, the legs and the bearing parts 2. Then, the printing device 6 is constituted so that the pins of the tips of the legs are inserted in the hole parts 10-a formed at the bottom surface of the printing device 6. When the covers 1-a are removed, it is good that the bearing parts 2 are pulled. When the covers 1-a are practically used, a member dedicated for aligning the drum 8 and a member dedicated for setting the upper cover are eliminated. |
