Abstract: There is provided an image formation apparatus that can prevent a system from having a reduced throughput even when the system includes an increased number of image formation apparatuses. When each MFP included in the system detects a presence of a user within a predefined range, the MFP notifies another MFP of the detection result. Each MFP determines, based on the detection result, a group of one or more MFPs from which the MFP of interest requests a list of one or more jobs issued by the user, more preferentially than another MFP, and the MFP of interest notifies another MFP accordingly.

Abstract: An image forming apparatus being capable of executing a plurality of functions comprises: an entry portion which allows a user to issue a request for using any one of the functions and enter user authority information; a display portion; an authenticator which: requires user authentication via a user authentication screen displayed on the display portion; and judges whether or not the user authority information entered via the entry portion is appropriate for an authorized user for the function; and a function execution controller which executes the function as requested, if the authenticator judges that the user authority information entered via the entry portion is appropriate for an authorized user for the function, wherein the authenticator resets the result of the user authentication if the function execution controller successfully finishes executing the function.

Abstract: An information processing device for installing and executing an application program which enables at least one of a plurality of information processing functions comprises: a storage part for storing functional restriction information configured for each of a plurality of users is defined; an obtaining part for obtaining, based on the functional restriction information, common functional restriction information in which restriction on use of at least one of the plurality of information processing functions except for a common available function commonly available for all the plurality of users is defined; a determination part, in installation of the application program, for determining whether or not a command contained in the application program enables an unavailable function restricted with the common functional restriction information by analyzing the command; a rewrite part for rewriting the command; and an installation part for installing the application program containing the command rewritten by the
