ABSTRACT:
An image forming apparatus that uses a thermal printing head (TPH) is provided. The image forming apparatus includes a platen roller. A TPH unit faces the platen roller and pivots to contact or separate from the platen roller. A first elastic member elastically biases the TPH unit toward the platen roller. A pair of cam levers are provided on both sides of the TPH unit. A pair of rotation cams contact the pair of cam levers and allow the TPH unit to pivot according to a rotation angle of the rotation cams.
