To provide an induction heating roller apparatus and an image formation apparatus capable of evenly heating a heating roller in an axial direction, easily performing insulation among a plurality of induction coils placed in a dispersed state and rendering a heating area of the heating roller switchable if desired. The induction heating roller apparatus has a heating roller HR for generating heat with an induction current by being magnetically coupled to an induction coil described later, a plurality of induction coils IC placed in a dispersed state in an axial direction inside the heating roller HR and also set in a relationship in which adjacent ones are in mutually reversed winding directions and generated flux has the same polarity, and a high frequency power supply for supplying high frequency power to the plurality of induction coils. The plurality of induction coils IC may be grouped into a plurality of induction coil groups IC1, IC2 and IC3.
