摘要： PROBLEM TO BE SOLVED: To realize the correction of a periodic variation of at least either density or a magnification along a subsidiary scanning direction in an image by a simple structure. SOLUTION: When the circumferential speed of a photoreceptor drum periodically varies depending on the eccentricity or the inclination of a rotary shaft due to a manufacturing error or the like (see (A)) and exposure is made on a line basis by making an exposure head having many LEDs arranged in a main scanning direction emit light, the variation of the circumferential speed of the photoreceptor drum appears as the variation of density (magnification)of an image along the subsidiary scanning direction (see (B)). Consequently, the variation of density (magnification) is corrected by changing the emission period of the exposure head during the formation of an image in accordance with the variation of the circumferential speed (see (C)).

摘要： PROBLEM TO BE SOLVED: To suppress a stripe-like defect occurring when a compensation is performed by shifting each region after an image of a skew correction or the like is divided into regions, and to suppress a picture quality defect, e. g. , in an image forming device using a multi-beam scanning optical system. SOLUTION: This image forming device comprises a plurality of light sources, and prints an image carrier by collectively scanning beams from the light sources. A control section 31 shifts an image in steps in a subsidiary scanning direction which is the moving direction of the image carrier when image data is drawn, and also shifts the image at different positions in a plurality of times of scannings to one scanning line in a multiple exposure. Also, the control section 31 divides the image data in a plurality of parts to a main scanning direction which is orthogonal to the moving direction of the image carrier, and also, in such a manner that the border line may become a shape other than the straight line of the subsidiary scanning direction, and draws a picture on a printing means by shifting the divided parts in steps in the subsidiary scanning direction.

摘要： PROBLEM TO BE SOLVED: To prevent wrapping and sticking of recording paper to a fixing unit without adjusting an amount of margins.
SOLUTION: The image forming apparatus 1 transfers a foaming toner to the leading end in the conveyance direction of the recording paper 10 in fixing the color image of deep mass density to the leading end in the conveyance direction of the paper in the case of the recording paper which is light in basis weight, is low in rigidity, and is smooth in the surface. When the portion transferred with the foaming toner passes between a heating roll 80 and pressure roll 81 of the fixing unit 11, the toner foams and a difference arises in the thicknesses of the images between the foamed portion and the portion not transferred with the foaming toner. An air layer is generated between the portion not transferred with the foaming toner and the heating roll 80 by the thickness of foamed toner and the recording paper 10 peels off from the heating roll 80, thereby preventing the recording paper 10 from wrapping and sticking to the heating roll 80 any more.

摘要： PROBLEM TO BE SOLVED: To accurately detect color shift and density by always making a distance between a sensor and a detection surface stable. SOLUTION: The position of a reading sensor 34 is varied in accordance with the thickness of paper P. Thus, the distance between the image forming surface of the paper P and the reading sensor 34 is always kept constant regardless of the thickness of the paper P. Thus, the reading sensor 34 accurately detects the color slurring and the density from a pattern for detecting deviation and a pattern for detecting density. Since the distance between the image forming surface of the paper P and the reading sensor 34 is kept constant in a non-contact state with the paper P without bringing a holding member or the like into contact with the paper P, the color shift and the density are accurately detected even when dust or the like adheres to the image forming surface of the paper P or even when embossed paper having ruggedness is used.

摘要： PROBLEM TO BE SOLVED: To prevent color shift caused by the skew of continuous sheet. SOLUTION: The skew state of the continuous sheet is detected by photosensors 64 and 66, and the skew amount of paper P is calculated in a control part 62 so as to move an LPH 30 and/or control the position and the light quantity of a light emitting element. Thus, color shift correction based on the skew information of the paper P is performed. Even for the continuous sheet that the paper P does not circulate, the skew state is detected and the color shift is corrected in accordance with the skew state, whereby the color shift caused by the change of the skew is prevented. By detecting the skew state and correcting the color shift, the color shift correction is performed not only in specified timing, for example, when starting the image forming apparatus 10 but also every time in accordance with the skew state, whereby the color shift is surely corrected.

摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of correctly informing a user of the need for maintenance in the case that fresh sheets and used sheets (sheets with an image formed on one side) are mixedly used. SOLUTION: The reference number of sheets, which corresponds to the reach of the end of the life of a conveying roller, is specified, for example, 10,000 for fresh sheets and 7,000 for used sheets. An axis of the abscissa of a characteristic line graph 53B represents the number X of fresh sheets subjected to printing and an axis of the ordinate of the characteristic line graph 53B represents the number Y of used sheets subjected to printing, and the reference number of the fresh sheets and the reference number of the used sheets are connected together with a straight line. The right side on the straight line (mathematical expression: Y=-0.7+7000 or X=-10/7Y+10000) is an area indicating the need for maintenance. For instance, in the case that the number Y of the used sheets subjected to printing is 700, the number X of the fresh sheets subjected to printing is 9000. When the number X of the fresh sheets exceeds 9000, a user is informed of the need for maintenance. COPYRIGHT: (C)2006,JPO&NCIPI
