An embossed component for positioning an article having a through hole includes a planar portion and an embossed portion projecting from a surface of the planar portion. The embossed portion is tapered toward a tip side and to be fitted into the through hole. The embossed portion includes a straight base end portion continuous with the planar portion and extending vertically with respect to the planar portion toward the tip side of the embossed portion, and an opening is at a tip of the embossed portion.

Embossed component and housing and image forming apparatus including same

A heat-resistant endless resin belt including a heat-resistant resin sheet, which can be employed in a thermal fixing apparatus, wherein the sheet includes two cutting work parts in an inclined shape. The two parts are overlapped with each other and bonded with an adhesive to form a bonding part. An external shape displacement f(x), measured via a flatness measuring apparatus, which scans the belt in a width direction thereof, satisfies a following formula wherein 'X' (mm) is a length of the belt in a width direction thereof; 'L' (mm) is a perimeter of the belt and &#x201c;g(x)&#x201d; represents a displacement of an ideal shape of the heat-resistant resin belt, when g(x)=C (a constant), a left side of the formula is set to be a minimum; whilst when g(x) is a variable, the displacement of the ideal shape of the belt is set.
