ABSTRACT:
An image forming device includes a thermal head, a head support portion, a platen roller, a pressing mechanism and a positioning portion. The thermal head prints in a printing direction. The head support portion rotatably supports the thermal head. The head support portion is supported at locations away from an imaginary line along the printing direction passing between the thermal head and the platen roller. The platen roller is disposed across from the thermal head. The pressing mechanism presses the thermal head against the platen roller during printing. The positioning portion comes into contact with the thermal head from the printing direction when the pressing mechanism presses the thermal head against the platen roller. The positioning portion positions the thermal head with respect to the platen roller along the printing direction.
