Patent number: 9081332Abstract: An image forming apparatus transfers a negative toner image on a waste sheet of paper having larger size than that of a printing sheet of paper and transfers all the toner images on the printing sheet of paper. A first thermal transferring portion transfers an unnecessary foil of a foil sheet on the negative toner image of the waste sheet of paper image. A second thermal transferring portion transfers a foil remained on the foil sheet on the positive toner image of the printing sheet of paper. The positive toner image is formed using transparent toner. Any gradation processing is performed on an edge of the positive toner image.Type: GrantFiled: May 14, 2013Date of Patent: July 14, 2015Assignee: KONICA MINOLTA, INC.Inventor: Tomoo Suzuki

Patent number: 9037065Abstract: In a first thermal transfer portion of upstream side, a negative toner image forming portion forms on a photosensitive drum a desired negative toner image which reverses a desired positive toner image selected from all the toner images. The negative toner image forming portion then forms the desired negative toner image on a belt member. The first thermal transfer portion transfers a desired negative foil image from a foil sheet to the belt member so that a desired positive foil image remains on the foil sheet. A second transfer portion transfers the desired positive foil image thus remained on the desired positive toner image formed on the sheet of paper. A cleaning portion removes the desired negative toner image and the desired negative foil image from the belt member.Type: GrantFiled: April 24, 2013Date of Patent: May 19, 2015Assignee: KONICA MINOLTA, INC.Inventor: Tomoo Suzuki

Patent number: 8886108Abstract: A second thermal transfer portion of upstream side transfers a foil image, to be not printed, from the foil sheet on a waste sheet, conveyed from an image forming apparatus, on which a desired negative toner image is transferred. The foil image, to be printed, remains on the transferred foil sheet. The waste sheet is ejected out of a foil transferring apparatus. A printing sheet of paper on which the desired positive toner image is transferred is conveyed from the image forming apparatus to a first thermal transfer portion of downstream side to meet time when the foil sheet on which the foil image, to be printed, remains reaches the first thermal transfer portion. The first thermal transfer portion transfers the foil image, to be printed, from the foil sheet on the conveyed printing sheet of paper on which the desired positive toner image is transferred.Type: GrantFiled: April 15, 2013Date of Patent: November 11, 2014Assignee: Konica Minolta, Inc.Inventor: Tomoo Suzuki
