Patent ID: 8619296

Claim:
An image forming apparatus comprising: a printing unit which prints an image on a print medium; a receiving unit which receives print job data from an external device connected to the image forming apparatus; a first circuit which creates image data on the basis of the print job data received by the receiving unit; a second circuit which causes the printing unit to print an image on the basis of the image data created by the first circuit and which is different from the first circuit; and a storage accessible by the first circuit and the second circuit, respectively and individually, via a connection to the storage, wherein the receiving unit inputs the print job data received from the external device to the second circuit, wherein the second circuit stores the print job data input by the receiving unit in the storage, and notifies the first circuit of the storing of the print job data via a communication channel, the communication channel being between the first circuit and the second circuit and being different from the connection to the storage, and wherein the first circuit, according to the notification by the second circuit, reads out the print job data stored in the storage from the storage via the connection to the storage and not via the second circuit, and creates image data on the basis of the read print job data.
