Abstract

An image forming apparatus includes a sheet conveyance portion, a recording portion, a sheet detection portion, and a control portion. In a duplex printing including a first and a second process of printing on a first surface and a second surface of the sheet, in the first process, the control portion calculates a center position of the sheet based on an edge position of the sheet on one side in the width direction and size information of the sheet, prints a first image on the first surface such that the first image is centered on the center position calculated, and prints a reference marker on the first surface. In the second process, the control portion calculates a correction magnification ratio based on a difference between a reading position and the printing position of the reference marker, and corrects a size and a printing position of a second image.
