Image forming apparatus and image forming method

An image forming method comprising:

• determining whether image data is digital book data;
• automatically displaying a digital book print mode for forming a book from the digital book data if the determination is that the image data is the digital book data;
• automatically controlling, based on the displayed digital book print mode, at least one of an image processing part that arithmetically processes the digital book data, an inversion conveyance part that inverts a sheet on one side of which an image is formed by an image forming part to form the image based on the digital book data on the sheet, and conveys the sheet to the image forming part, and a finishing part that finishes the sheet on which the image is formed by the image forming part;
• and
• forming a book by an image forming apparatus including the image processing part, the inversion conveyance part and the finishing part which are controlled based on the digital book print mode, and the image forming part.

• determining whether image data is digital book data;
• automatically displaying a digital book print mode for forming a book from the digital book data if the determination is that the image data is the digital book data;
• automatically controlling, based on the displayed digital book print mode, an image processing part that performs an optimum arithmetic processing for forming the book on the digital book data, an inversion conveyance part that inverts a sheet on one side of which an image is formed by an image forming part to form the image based on the digital book data on the sheet, and conveys the sheet to the image forming part, and a finishing part that includes a saddle stitch part to staple a center part of the sheet on which the image is formed by the image forming part and to fold the sheet in two along the center part of the sheet;
• and
• forming the book by an image forming apparatus including the image processing part, the inversion conveyance part and the finishing part which are controlled based on the digital book print mode, and the image forming part.
