Patent ID: 7859690

Claim:
An image forming apparatus comprising: an image reading section configured to read out an image from a document and output its image data; an image data memory section configured to store the image data which is output from the image reading section; an image forming section configured to form the image on a sheet based on the image data which is output from the image data memory section; a memory section configured to store a print setting including a setting of a number of print copies and a first value; a proof copy button configured to set a proof copy mode for proof copying, during which only one of the print copies is allowed to be image formed based on the print setting and the image data before an interrupt process is initiated during which image forming of remaining print copies is interrupted and additional proof copying is carried out; a control section configured to restrict the additional proof copying during the interrupt process if the number of times the additional proof copying has been carried out during the interrupt process is equal to or greater than the first value stored in the memory section; a control panel having a touch panel on which the proof copy button is formed; and a display control section configured to make the proof copy button unavailable to be selected when the control section restricts the additional proof copying.
