Abstract:
An image forming apparatus comprising:a platen roller; a head to be pressed against the platen roller, and forming an image onto a recording medium; a first impelling member impelling so as to press the head against the platen roller; an impelling roller to be pressed against the platen roller; a second impelling member impelling so as to press the impelling roller against the platen roller; and a pressure contact releasing mechanism resisting an impelling force of the second impelling member to hold the impelling roller in a waiting position in which the impelling roller does not press against the platen roller; wherein while the head is pressed against the platen roller by use of the first impelling member and the recording medium supplied between the head and the platen roller is pressed, and while the impelling roller is pressed against the platen roller by use of the second impelling member, the recording medium is transported as the image is formed thereonto; and wherein the pressure contact releasing mechanism resists an impelling force of the first impelling member to hold the head in a position in which the head does not press against the platen roller.
