Abstract
The present invention provides a self-heating fuser roller including a tubular resistor layer that generates heat by being supplied with electricity, in which the resistor layer has a plurality of slits. The slits are preferably disposed at regular intervals in a circumferential direction. The slits preferably extend in an axial direction. Preferably, the slits are not provided on both end edges in an axial direction. The slits preferably have an average width of 50 μm or more and 2 mm or less. The slits preferably have an average interval of 30 μm or more and 1 mm or less. The slits are preferably filled with a resin composition. The resistor layer preferably includes a resin matrix and a plurality of electrically conductive particles contained in the resin matrix.
