Abstract: An image forming apparatus includes a function performance information storage section, a function performance information receiving section, and a function selection section. The function performance information storage section stores function performance information of the image forming apparatus. The function performance information receiving section receives the function performance information of the mobile terminal. The function selection section compares the function performance information of the image forming apparatus with the function performance information of the mobile terminal to select the function for which the performance of the image forming apparatus is determined to be superior. The image forming apparatus transmits the information representing the function which is not selected by the function selection section to the mobile terminal, and performs the processing of the function selected by the function selection section.

Abstract: In a case where a set value, which is used during a time of job execution by an image forming apparatus that is different from the use-target image forming apparatus, is selected as a set value to be set into a use-target image forming apparatus, based on set value identification information, an information processing apparatus of an image forming system identifies a set value corresponding to the selected set value from set values for a set item of the use-target image forming apparatus, and transmits setting information, which is for changing a current set value of the use-target image forming apparatus to the identified set value, to the use-target image forming apparatus.

Abstract: A image reading device comprises a reading part for reading a document, a storage part including shared space, and an operation part for accepting input of identification information when the device is in a logged-out state, entering a logged-in state when a user is successfully certified, accepting settings input and function execution input when the logged-in state is in effect, and entering the logged-out state when predetermined conditions are met, the operation part including a scanning START key for accepting instructions to perform scanning using the reading part. When the scanning START key is pressed while the device is in the logged-out state, the reading part reads a document and forms image data, and the storage part stores the image data formed by logged-out scanning in the shared space.
