Patent ID: 8502992

Claim:
An image forming system, comprising: an image formation unit for forming an image relating to a job currently under output on a paper; a first paper ejection unit for receiving the paper on which the image is formed; a second paper ejection unit for receiving the paper as a sample paper on which the image is formed in a state that the sample paper is visually checked when sample paper ejection is performed; a switching section for switching a paper sending destination between the first paper ejection unit and the second paper ejection unit; a first control section for controlling the switching section to eject the sample paper by switching the paper sending destination from the first paper ejection unit to the second paper ejection unit at a time of the sample paper ejection; a storing section for storing image data of the image relating to the job; a second control section for controlling a display section to display thumbnail images of already output pages of the job currently under output, based on the image data stored in the storing section; and a selecting section for selecting the image for sample paper ejection to be used for the sample paper ejection from the thumbnail images displayed in the display section by the second control section, on the basis of a user's operation, wherein the first control section performs the sample paper ejection using the image for sample paper ejection selected by the selecting section, and wherein when the image for sample paper ejection is selected by the selecting section on the basis of the user's operation during image forming processing by the image formation unit of the job currently under output, and if the selected image for sample paper ejection is an image scheduled to be output to the first paper ejection unit, then the first control section performs the sample paper ejection at output timing when the scheduled image is output to the first paper ejection unit.
