Abstract: According to an embodiment, an image elimination apparatus eliminates an image formed on a sheet. A sheet supply unit supplies the sheet on which the image is formed. A first reader reads the sheet supplied by the sheet supply unit. An image eliminator eliminates the image formed on the supplied sheet. A second reader reads the sheet passing through the image eliminator. A discharge unit stacks the sheet to be discharged. A controller causes the first reader to read the sheet at a first speed in order to judge whether the sheet is reusable or not based on the reading result of the first reader. The controller also causes the second reader to read the sheet at a second speed faster than the first speed in order to judge whether the image formed on the sheet has been eliminated or not based on the reading result of the second reader.
