Abstract: An image processing apparatus having various interrupt-handling capabilities when image formation is interrupted. In one aspect, image formation is interrupted after completion of a predetermined number of image formations when the size of a recording material is indicated as a first size, and image formation is interrupted after a completion of a predetermined number of image formations when a recording material is indicated as a second size. In another aspect, a condition for image formation is selected whereby in the case the selected condition is prevented (e.g., recording on wrong-sized paper), the condition is stored, and after the image formation has commenced, a stop command is inhibited and stored. In another aspect, data concerning image information is entered, the entered data is displayed, and images are formed sequentially in accordance with the data whereby the formation of the images may be interrupted and the remaining number of image formations may be stored and displayed.
