A method of manufacturing a heating device includes preparing a substrate having a curved surface; and forming a heating body on the substrate, the heating body generating heat with a supply of electric current. The forming of the heating body includes pressing a screen toward the substrate with an aid of a pressing member while rotating the substrate and moving the screen, and transferring application liquid that is to form the heating body to the substrate through the screen. In the forming of the heating body, the pressing member is in contact with the screen at a position on an upstream side with respect to a transfer position in a direction of movement of the screen.

A substrate support includes a drum, a first surface carried by the drum, and a second surface carried by the drum opposite and oblique to the first surface and a wedging member. The wedging member is sandwiched between the first surface and the second surface and is resiliently biased in a wedging direction.

An image forming apparatus includes a transfer unit that comes into contact with an object to transfer an image to the object, a facing unit that moves together with the object in a transport direction of the object to bring the object into contact with the transfer unit, and a mechanism that brings the facing unit closer to the transfer unit in accordance with movement of the facing unit in the transport to bring the object into contact with the transfer unit and then further brings the facing unit and the transfer unit closer to each other.
