Image forming apparatus

摘要

An image forming apparatus acquires an amount of deflection of the transporting sheet from a reference position thereof and calculates a required shift amount of the sheet. It determines whether or not the sheet is shifted frontward. If so, the image forming apparatus acquires a second specified shift value which is set by taking an urging force into consideration using a second correction equation. Alternatively, if the sheet is shifted backward, the image forming apparatus acquires a first specified shift value which is set by taking the urging force into consideration using a first correction equation. The image forming apparatus performs a registration roller shift correction based on the acquired first or second specified shift value.
