An image forming apparatus can carry out a continuous enlargement process by which an image of one original is enlarged and the image is formed on a plurality of sheets. According to the continuous enlargement process, a size of an original is first set, and a size of an image to be output can be input. A range of a size of an image to be output which can be input is calculated considering the size of the original and an ability of the apparatus. If the input size of the image to be output is within the range which can be input, a copy is made according to the continuous enlargement process. A user can input an arbitrary size within the range which can be input. Accordingly, the image forming apparatus can be provided which can form an image of an output size desired by a user when a size of an image of an original is to be changed and an image is formed on sheets of the number which is different from that of the original.
