<P>PROBLEM TO BE SOLVED: To simply and effectively correct deflection of a developing roller due to push pressure of a pressure contact member while obtaining high image quality by lessening a developing gap as much as possible. <P>SOLUTION: A development cartridge 1 is constituted as a photoreceptor development machine integrated cartridge integrating a photoreceptor 2 and a development machine 3. The photoreceptor 2 and the developing roller 5 are supported with the same support members 4a and 4b of a photoreceptor development machine integrated case 4. Sheet-like spacers 11 and 12 fixed on both the ends of the developing roller 5 are pressure contacted on the surface of the photoreceptor 2. Furthermore, a feed roller 6 is pressure contacted on the developing roller 5, and the photoreceptor 2 is pressure contacted oppositely or substantially oppositely in a direction of force F2' that pushes the developing roller. The deflection of the developing roller 5 due to pressure contact of the feed roller 6 is corrected to be returned by force F' of reaction of push pressure F2 due to pressure contact to the photoreceptor 2 of the developing roller 5. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
