It is configured to output on different transfer papers P. Therefore, the user can make a copy larger than the transfer paper P of the maximum size of the copying machine by laminating the plurality of transfer papers P without performing accurate positioning (Japanese Patent Application Laid-Open No. 62-230262).

13 and 14 show the operation of the conventional image forming apparatus. First, the user sets the enlarged continuous shooting mode (step S1), and then the document area (x ₁ ,
y ₁ ), (x ₂ , y ₂ ) and the size of the transfer paper (x _p , y
_p ) and the magnification A are specified (step S2), the output image length x _out = A * (x ₂ −x ₁ ), y _out = A * (y ₂
-Y ₁ ) is calculated (step S3), and then the number of output sheets x
_num and y _num are calculated (steps S4 to S8). Then, the output area x _point , y of the original image is transferred for each transfer sheet.
Corners are set by setting a _point, and output is performed according to the scaling factor (steps S9 to S26). It should be noted that, in the figure, since it is smaller when expressed as a subscript, they are not shown as a subscript and are directly arranged. The same applies hereinafter.

[0004]

However, in the above-mentioned conventional image forming apparatus, since the original image is divided according to the size and magnification of the original and the transfer paper regardless of the original image, the user does not want to combine the portions. There is a problem that the image is divided. For example, as shown in FIG. 12, even when the user wants to output only one person's face portion on a document without dividing it, it is cut at that portion. It is necessary to shift the placement position, change the area, and output again, and the paper is wasted.
