1. An apparatus, comprising:
- a mass to store heat;
a first heater to heat the mass;
a device to measure power provided by a power source;
a second heater; and
a controller to maintain a sum of a level of power supplied to the first heater and a level of power supplied to the second heater within a range of a predetermined value using a measurement of a level of the power provided by the power source,wherein the mass, the first heater, the device, the second heater, and the controller are included in an image forming system,wherein the controller is configured to linearly increase power to the second heater and stop power to the first heater when the system is transitioning to an image forming mode, and stop power to the second heater and linearly decrease power to the first heater when the system is transitioning from the image forming mode.

11. An apparatus, comprising:
-
a mass to store heat; a first heater to heat the mass; a device to measure first-power provided by a power source; a second heater; and means to maintain a sum of a level of power to be supplied to the first heater and a level of power to be supplied to the second heater within a range of a predetermined value using a measurement of a level of the power provided by the power source, wherein the mass, the first heater, the device, the second heater, and the means to maintain are included in an image forming system, wherein the means to maintain linearly increases power to the second heater and stops power to the first heater when the system transitions to an image forming mode, and stops power to the second heater and linearly decreases power to the first heater when the system transitions from the image forming mode.
