calculate a first maintenance score for each of a plurality of first maintenance persons who have performed maintenance on one or more of the plurality of image forming apparatuses used by a first user, and

correct the maintenance priority based on the first maintenance scores.

4. The maintenance support system according to claim 3 , wherein the processor is further configured to:

calculate a second maintenance score for each of a plurality of second maintenance persons who have not performed maintenance on one or more of the plurality of image forming apparatuses used by the first user,

compare a first average of the first maintenance scores with a second average of the first maintenance scores and the second maintenance scores, and

correct the maintenance priority based on a comparison result of the first and second averages.

5. A method carried out by a maintenance support system configured to communicate with a plurality of image forming apparatuses that are used by, and are to be maintained for, a plurality of users, the method comprising:

acquiring:

apparatus information about each of the plurality of image forming apparatuses, the apparatus information indicating the number of errors occurred in the image forming apparatus, a use state of a reused toner in the image forming apparatus, a lot number of each of components attached to the image forming apparatus, the number of the components of which service lives have expired, and a last visit date by a maintenance person for maintenance on the image forming apparatus,

usage information indicating a use state of each of the plurality of image forming apparatuses, the usage information indicating a month in which the image forming apparatus is most frequently used, a call occurrence rate of calls received from the user about the image forming apparatus, and the number of communication devices connected to the image forming apparatus, and

contract information about contracts made with the users to provide maintenance services, the contract information indicating a contract term;

when an error occurs in one of the image forming apparatuses, determining a maintenance priority of the image forming apparatus based on the apparatus information, the usage information, and the contract information; and

recording the determined maintenance priority in a memory.

6. The method according to claim 5 , further comprising:

storing in the memory:

an image forming apparatus table which has a plurality of image forming apparatus records each indicating the use state of a reused toner, the contract term, and the call occurrence rate of one of the image forming apparatuses and the month in which the image forming apparatus is most frequently used,

an error information table which has a plurality of error information records corresponding to errors occurred in the plurality of image forming apparatuses,

a connected device number table which has a plurality of connected device number records each including the number of communication devices connected to one of the plurality of image forming apparatuses,

a component counter table which has a plurality of component counter records each including a counter value of a component of one of the plurality of image forming apparatuses,

a caution lot table which has a plurality of caution lot records each indicating a lot number of a specific component that requires caution,

a call information table which has a plurality of call information records each including information about a call received from a user about one of the image forming apparatuses, and

a maintenance information table which has a plurality of maintenance information records each indicating a maintenance service provided on one of the plurality of image forming apparatuses.

7. A method carried out by a maintenance support system configured to communicate with a plurality of image forming apparatuses that are used by, and are to be maintained for, a plurality of users, the method comprising:

acquiring:

apparatus information about each of the plurality of image forming apparatuses,

usage information indicating a use state of each of the plurality of image forming apparatuses, and

contract information about contracts made with the users to provide maintenance services;

when an error occurs in one of the image forming apparatuses, determining a maintenance priority of the image forming apparatus based on at least one of the apparatus information, the usage information, and the contract information;

recording the determined maintenance priority in a memory;

calculating a first maintenance score for each of a plurality of first maintenance persons who have performed maintenance on one or more of the plurality of image forming apparatuses used by a first user; and
