Fixing device and image forming apparatus

A fixing device comprising:

• an endless fixing belt;
• a press roller arranged on an outer peripheral side of the fixing belt;
• a nip pad which is arranged on an inner peripheral side of the fixing belt and faces the press roller through the fixing belt;
• and
• a friction reducing member sandwiched between the nip pad and the fixing belt, wherein
• a thermal conductivity of the friction reducing member is larger than a thermal conductivity of the nip pad,
• a length L1 of the friction reducing member in a width direction of the fixing belt is equal to a length L2 of the nip pad in the width direction of the fixing belt or is larger than the length L2 of the nip pad in the width direction of the fixing belt,
• the fixing belt includes a conductive layer,
• an induced current generation part is arranged on the outer peripheral side of the fixing belt and at a position avoiding the press roller, and heats the conductive layer by electromagnetic induction,
• the length L1 of the friction reducing member in the width direction of the fixing belt is equal to a length L3 of the induced current generation part in the width direction of the fixing belt or is larger than the length L3 of the induced current generation part in the width direction of the fixing belt, and
• the length L1 of the friction reducing member in the width direction of the fixing belt is less than a width of the fixing belt.
