摘要： PROBLEM TO BE SOLVED: To improve detecting accuracy at the front edge of a sheet, in a sheet carrying device detecting the front edge of the sheet and an image forming device such as a copier, a printer and a facsimile having the sheet carrying device. SOLUTION: This image forming device includes assist roller pairs 10 and skew correcting roller pairs 21 and 22 for carrying a succeeding sheet S in the width direction to a preceding sheet in an offset state, and a register sensor 131 for detecting the front edge St of an offset part Sa of the succeeding sheet S. The image forming device also has register roller pairs 30 for shifting the succeeding sheet S the front edge of which is detected by the register sensor 131 in the opposite direction of the offset direction.

摘要： The present invention provides an image forming apparatus which can increase the life of a fixing roller without causing increase of the apparatus in size and image displacement. A first skew feeding and registration correcting portion 1 and a second skew feeding and registration correcting portion are controlled so as to move the sheet in a first direction in a width direction in correcting a side end position of a sheet by the first skew feeding and registration correcting portion and to move the sheet in stages in a second direction in the width direction which is opposite to the first direction in the width direction in correcting the side end position of the sheet by the second skew feeding and registration correcting portion.

摘要： A sheet conveying apparatus has a skew conveying correction roller pair 2 for conveying a sheet, skew conveying detection sensors 3a and 3b for respectively detecting a skew of a sheet and a sheet-end-position detection sensor 4 for detecting the side position of the sheet. The skew conveying correction roller pair 2 is skewed by a skew amount obtained by adding a first skew amount for correcting the skew of a sheet detected by the skew conveying detection sensor 3a and 3b and a second skew amount theta2 for correcting the side position of a sheet detected by the sheet-end-position detection sensor 4. After the sheet is nipped by the skew conveying correction roller pair 2, the skew conveying correction roller pair 2 is skewed by the first skew amount theta1.

摘要： PROBLEM TO BE SOLVED: To carry out the alignment of both surfaces of an image at a high level by mutually matching exclusive reading patterns for positioning of a 1st surface and a 2nd surface. SOLUTION: In this image forming device, the exclusive positioning marks #1 to #4 are formed in blank spaces of a sheet material S that is already fixed, the marks #1 to #4 are read by a 1st CCD line sensor 74 provided inside a paper refeeding path and magnification in a main scanning direction and a sub scanning direction on a 2nd surface are compensated. The marks #1 to #4 are read by a 2nd CCD line sensor installed upstream of a carrying belt and image position correction in a main scanning direction, a sub scanning direction and a rotating direction on a 2nd surface is carried out.

摘要： PROBLEM TO BE SOLVED: To provide an image forming device capable of always keeping an image position constant even in a sheet on which an angle formed by the distal end and the side end is not a right angle. SOLUTION: When carrying the sheet S on which the angle formed by the distal end and the side end is not the right angle, when setting one side end of the sheet S in parallel to the sheet carrying direction, a skew correction quantity by skew correction roller pairs 21 and 22 is adjusted by a skew correction quantity adjusting part. When correcting a skew of the sheet S, a side end position correction quantity of register roller pairs 30 is adjusted based on an adjusting quantity of the skew correction quantity by the skew correction quantity adjusting part by a side end position correction quantity adjusting part.
