Image fixing apparatus having two fixing units and image forming apparatus

摘要

An image fixing apparatus includes a first conveying path on which a sheet is conveyed, a first fixing unit that fixes a toner image on a sheet conveyed on the first conveying path, a second conveying path on which a sheet is conveyed, wherein the second conveying path branches from the first conveying path in a bifurcation provided on a upstream of the first fixing unit and joins into the first conveying path in a confluence provided on a downstream of the first fixing unit, and a second fixing unit provided on a upstream of the bifurcation or on a downstream of the confluence or on the second conveying path. Time to convey a sheet from the bifurcation to the confluence through the first conveying path and time to convey a sheet from the bifurcation to the confluence through the bypass conveying path are nearly equal.
