A portion of a fixing lamp is formed in a lamp cartridge which includes a first lamp holder for holding one end of the fixing lamp; a second lamp holder for holding the other end of the fixing lamp; and a protective member holding portion for holding a lamp protective member which is attached depending on necessity. The protective member holding portion is arranged around a region where the lamp holding member is placed, and, thereby, all of the plurality of fixing lamps are capable of being attached to and removed from the heating roller as a unit from one end of the heating roller.
