Abstract
When a comparative determination portion determines that passage of a sheet through a reference position is lagged based on a detecting signal from a passing timing detection unit, a sheet conveying speed of a skew feeding correction roller on the same side as that of a sensor which detects the lagged sheet in two sensors is increased to correct sheet skew feeding. When the comparative determination portion determines that passage of a sheet through a reference position is leaded, the sheet conveying speed of the skew feeding correction roller on the same side as that of a sensor which detects the leaded sheet in the two sensors is reduced to correct sheet skew feeding.
