Japanese Patent JP2019043748
Kind Code:
A
Abstract:
To provide an image formation device capable of accurately determining a size of a loop at the sheet width direction end position of a sheet to be conveyed.SOLUTION: An image formation device 10 has: loop detection members (R side) 60a and (L side) 60b which are arranged in a plural number in a sheet width direction perpendicular to a sheet conveying direction, and between a transfer roller 17 and a fixing unit 19, and are displaced according to the loop amount of a sheet S to be conveyed; and a CPU 104 which changes the sheet-conveying speed of the fixing unit 19 according to the displacement of the loop detection members (R side) 60a and (L side) 60b. The CPU 104 controls the timing to change the sheet-conveying speed on the basis of the sheet width direction size of the sheet S to be conveyed, when the displacement amounts between the plurality of loop detection members (R side) 60a and (L side) 60b differ from each other.SELECTED DRAWING: Figure 2
