Fixing device and image forming apparatus

A fixing device that fixes a toner image on a recording material, the fixing device comprising:

• a rotatable endless belt member including a first surface that abuts on the recording material and a second surface opposite the first surface and to which a lubricant is applied;
• a nip forming member provided inside the belt member;
• a pressure rotating body configured to form a fixing nip portion that nips and conveys the recording material together with the belt member by pressurizing the nip forming member via the belt member;
• a rotatable rotating member including a third surface that abuts on the second surface of the belt member;
• and
• a lubricant regulating member configured to abut on the third surface of the rotating member and provided at a position straddling each of at least both ends of the belt member in a width direction perpendicular to the conveying direction of the recording material, and inclined downstream in a rotation direction of the rotating member toward the central portion in the width direction of the belt member.
