Induction-heating fixing apparatus and image forming apparatus

An induction-heating fixing apparatus comprising:

• a heating member for fixing a toner image to a recording material carrying the toner image by heating the toner image;
• an induction-heating coil divided into a plurality of coils and comprising a first induction-heating coil and a second induction-heating coil adjacent to each other;
• and
• a power-distribution control member for controlling power distribution by supplying a driving-current to the plurality of induction-heating coils in order to heat the heating member,
• wherein the power-distribution control member performs control so as not to supply the driving-current to the second induction-heating coil when the driving-current is supplied to the first induction-heating coil or so as not to supply the driving-current to the first induction-heating coil when the driving-current is supplied to the second induction-heating coil.

An image forming apparatus comprising:

• an image carrying body for carrying a toner image;
• a transfer member for transferring the toner image carried by the image carrying body to a recording material;
• and
• an induction-heating fixing apparatus for fixing the toner image to the recording material carrying the toner image, the induction-heating fixing apparatus comprising a heating member for fixing the toner image to the recording material carrying the toner image by heating the toner-image, an induction-heating coil divided into a plurality of coils and comprising a first induction-heating coil and a second induction-heating coil adjacent to each other, and a power-distribution control member for controlling power distribution by supplying a driving-current to the plurality of induction-heating coils in order to heat the heating member,
• wherein the power-distribution control member comprises a determining section for selecting whether to supply the driving-current to the first induction-heating coil or the second induction-heating coil.
