  • Patent number: 8998371
    Abstract: An image forming apparatus includes an image forming device, a conveyance unit, a correction unit, and an attitude controller. The image forming device forms an image on a printing medium. The conveyance unit is disposed opposing the image forming device to convey the printing medium. The correction unit corrects an attitude of a leading edge of the printing medium sent out from the conveyance unit. The attitude controller controls correction of the attitude of the leading edge of the punting medium performed by the correction unit. The attitude controller determines whether or not the correction of the attitude of the leading edge of the printing medium is to be performed, and causes the correction unit to perform the correction when the attitude controller determines that the correction is to be performed.

  • Publication number: 20150077456
    Abstract: An image forming apparatus includes a media roll, an image forming device, a conveyance unit, and a controller. In the roll, a printing medium having an adhesive face and no separation sheet on the adhesive face is wound in a roll shape. In pulling back the medium to the roll, the controller sets a linear velocity of the roll to be not over than a linear velocity of a conveyance rotator of the conveyance unit. The controller controls a velocity difference between the roll and the rotator to be Va from a start of pulling back the medium to when a separation point of the medium from the roll reaches a tangent line of the roll in an area between the roll and the rotator. When the separation point reaches the tangent line, the controller switches the velocity difference from Va to Vb that is smaller than Va.
