An image processing apparatus is provided which includes an image obtaining member which obtains an original image and outputs data of the original image. In the image processing apparatus, unique additional image data is merged to the original image data. A memory stores the original image data and the merged image data, and an image is formed based on the formed merged image data. In a first image processing mode, the merged image data is formed before the original data is stored to the memory, and the merged image data is then stored to the memory and an image is formed based on the stored merged image data. In a second image processing mode, the original image data is stored to the memory before forming the merged image data. Then the merged image data is formed, and an image is formed based on the formed merged image data.

Disclosed is an image forming apparatus that prints a confidential image on a recording medium. The apparatus includes a display, a printer for printing images in a queue, an input for receiving identification information for a user, and a processor. The processor determines whether identification information from the input corresponds to reference identification information in a storage and enables the printer to print a confidential image if the identification information from the input corresponds to the reference identification information in the storage.
