Image forming apparatus configured for rolled printing media having adhesive face

An image forming apparatus, comprising:

• a media roll in which a printing medium having an adhesive face is wound in a roll shape;
• an image folining device to form an image on the printing medium;
• and
• a feeder to feed the printing medium, the feeder including:
• a protection belt to press against and protect the adhesive face of the printing medium;
• a pair of rotary bodies disposed opposing each other to sandwich and press the protection belt and the printing medium including the adhesive face between the pair of rotary bodies, wherein one rotary body in the pair of rotary bodies presses the combination of the printing medium and the protection belt against the other rotary body amongst the pair of rotary bodies;
• and
• an auxiliary rotary body disposed between the media roll and the pair of rotary bodies and configured to be movable to a position for defining an approach angle of the printing medium to be within a range from 0° to 30° when the printing medium includes the adhesive face is to be fed, and movable to another position for defining the approach angle to be greater than 30° when a medium that does not include an adhesive face is to be fed, the approach angle being formed by the printing medium drawn from the media roll and approaching to between the pair of rotary bodies and an opposing face of the protection belt opposing the image forming device.
