An image forming apparatus includes an attachment portion to which any one of a first fixing apparatus and a second fixing apparatus is selectively attached, and a power supply circuit including a plurality of power supply paths. The first fixing apparatus includes a plurality of first heating elements grouped into a plurality of groups, and a number of the plurality of groups is equal to a number of the plurality of power supply paths. The second fixing apparatus includes at least one second heating element grouped into at least one group whose number is smaller than the number of the power supply paths. In a state where the second fixing apparatus is attached to the image forming apparatus, a power supply path of the plurality of power supply paths in which a power line has a largest allowable current value is electrically connected with the at least one second heating element.
