摘要： In a first process, initial dot pattern of a predetermined dot rate “a” is created in a first process, and a gradation value corresponding to the dot rate “a” is arranged as a threshold value in the position of the pixel of the threshold value matrix corresponding to the initial dot pattern. Then in a second process, the initial dot pattern or the dot pattern having occurred prior to the second computation is used as the dot pattern of dot rate “b”, and new dots including the dots of the dot pattern of dot rate “b” is generated or any of the dots is removed from the dot pattern of the dot rate “b” by the error diffusion method. Thus, the dot pattern of the next dot rate “b′” with its dot rate having been increased or decreased in the aforementioned procedure is generated.

摘要： It is an object of the present invention to provide a bearing member having a highly accurate dynamic pressure generating portion stably at low cost. Dynamic pressure grooves (8a1) and (8a2) are formed as the dynamic pressure generating portions on an inner circumferential surface of the electroforming portion (10) by an electroforming process, and injection molding is performed by using a resin while inserting the electroforming portion (10), thereby forming a bearing member (8). A shaft member (2) is inserted into an inner circumference of the bearing member.

摘要： There is described an image forming apparatus, which can conduct the countermeasure for eliminating an ink clogging defect with accuracy lower than a recording element arrangement resolution. The apparatus includes a defect position detecting section to detect a defect position at which no recording material is outputted; a defect position specifying section to specify a defect recording element, which resides at the defect position, and a kind of recording material to be outputted by the defect recording element; a mixture ratio determining section to determine a mixture ratio of plural recording materials, so as to make the mixture ratio of a specific recording material to be outputted by plural recording elements residing in a peripheral area of the defect position and including the defect recording element, decrease to a value lower than a normal mixture ratio, while using the normal mixture ratio for other recording elements residing in other areas.
