An image heating apparatus for heating a toner image formed on a recording material includes a first rotatable member contactable to the toner image; and a heating unit, including a second rotatable member rotating while contacting a surface of the first rotatable member, for heating the first rotatable member. The toner image on the recording material is heated by receiving heat from the first rotatable member heated by the heating unit. The image heating apparatus further includes a potential controller for maintaining a polarity of a surface potential of the second rotatable member so as to be opposite to a charge polarity of the toner.

It is also an object of the present invention to provide objective advertisement plan(s). The target specifying information storage means 2 stores information for specifying target attribution including information for specifying information delivery medium of an object to contact with correspondently with searchers' id. The search term storage means 3 correspondently stores a searcher's id, the timing of search, and the term used for the search. The extraction means 4 extracts the timing of search for such search term for each searcher's id, segments the extracted search timing for each searcher's id into a predetermined number in chronological order and then extracts searcher's id belonging to each segment. The advertising medium data determination means 5 extracts information on candidate of information delivery medium for the each segment from the extracted each searcher's id using information for specifying a target and determines candidate(s) of information delivery medium from the extracted candidate of information delivery medium.
