The present invention is intended to improve operability of an image processing device by reading a document with multiple pages at a time, changing a page addressed to each destination, and transmitting the page to each destination. In order to achieve this, an image processing device 1 for example comprises: a scanner unit 2 for reading a document with multiple pages and for generating image data; a destination setting part 52 for setting a plurality of destinations to which the image data generated by the scanner unit 2 are addressed; a transmission page setting part 53 for selecting at least one page addressed to each of the plurality of destinations from the multiple pages for which the image data are generated by the scanner unit 2, and for setting the selected page as a transmission page addressed to each destination; a file creation part 54 for creating a transmission file containing the image data of the selected page to be transmitted to each destination based on the transmission page set for each destination by the transmission page setting part 53; and a file transmission part 55 for individually transmitting the transmission file created by the file creation part 54 to each destination.
