1. A fixing device, configured to heat and fix a toner image formed on a sheet to the sheet, comprising:
a heat roller that heats the toner image formed on the sheet;
a ground contact that grounds the heat roller; and
a housing, wherein
the ground contact includes:
a first electrical conductive member that is electrically connected to the heat roller;
a second electrical conductive member that grounds the heat roller via the first electric conductive member; and
an electrical insulating member that is interposed between the first electrical conductive member and the second electrical conductive member and that insulates the first electrical conductive member and the second electrical conductive member from each other,
the electrical insulating member is a sheet member having a predetermined thickness, and interposed between the first electrical conductive member that faces a first surface of the electrical insulating member and the second electrical conductive member that faces a second surface of the electrical insulating member,
the housing includes a convex portion that allows the ground contact to be attached thereto, and
each of the first electrical conductive member, the second electrical conductive member, and the electrical insulating member includes a hole into which the convex portion is to be fitted.
