Abstract
In a method and an apparatus for removing an image forming substance such as toner from an image holding member such as a sheet of transfer paper, a liquid providing unit is constructed by plural coating devices such as three coating devices each having a coating roller, a restricting roller and a liquid container for liquid storage. The coating devices are arranged along a conveying path of the transfer paper sheet. A liquid is provided to the transfer paper sheet from both face sides thereof by using a mist generator, etc. in the liquid providing unit. The coating and restricting rollers are arranged such that no coating and restricting rollers come in contact with the transfer paper sheet so as not to restrict the transfer paper sheet. A surface of each of the coating and restricting rollers is desirably constructed such that this surface is hydrophilic. Another toner removing apparatus is also shown. A drive roller device for supporting an offset belt for conveying the transfer paper sheet is also shown.
