Abstract: A fixing belt includes a base member containing a metal, a sliding layer containing a filler and formed on a base member inner side, and a separation layer formed on a base member outer side. Assume that (i) a sliding layer cross section is obtained by cutting the sliding layer along a sliding layer thickness direction and is divided into sections each having a length that is the same as a sliding layer thickness in a direction perpendicular to the thickness direction, and (ii) a ratio of a filler area to a sliding layer area in each cross section sections is an area ratio. A period coefficient is calculated using the formula (Ave %?Min %)/Ave %, where an average of area ratios of filler areas in all the sections is Ave % and a minimum of the area ratios is Min %, and the calculated period coefficient is 0.6 or more.

Abstract: A play data editing device edits play data according to a characteristic of a speaker. The play data editing device includes a dividing unit (301) for dividing first play data into second play data per channel; a classifying unit (302) for classifying the second play data into a rhythm part, a melody part, and a base part; a chord processing unit (303) for converting a number of chords of the second play data corresponding to the melody part according to the characteristic of the speaker; a velocity processing unit (304) for converting a velocity of the second play data corresponding to the rhythm part according to the characteristic of the speaker; and a sound range processing unit (305) for shifting a sound range of the second play data corresponding to the base part according to the characteristic of the speaker.
