Abstract
An image forming device detects a standard pattern transferred to a transfer belt by an image carrier. The standard pattern is transferred onto the transfer belt at an image transfer position and detected at a standard pattern detection position. The distance between the image transfer position and the standard pattern detection position is a non-integer-multiple of the distance which the transfer belt is moved by one rotation of the image belt drive roll.
