Claim:
1. A control device that controls a heating device comprising a plurality of heating zones, the control device comprising: a monitoring unit configured to monitor a temperature of at least a first heating zone in the plurality of heating zones; a control unit configured to perform heat-up starting control, in which heat-up of at least a second heating zone is started in the plurality of heating zones, based on the temperature of the first heating zone, a threshold setting unit configured to set the threshold, wherein the temperature of the first heating zone is adjusted to a first setting temperature, wherein the temperature of the second heating zone is adjusted to a second setting temperature, wherein the threshold setting unit updates the threshold based on a first temperature difference or a second temperature difference in a previous heat-up starting control performed by the control unit, wherein the first temperature difference is a temperature difference between a temperature of the second heating zone at a time when the first heating zone reaches the first setting temperature and the second setting temperature, and wherein the second temperature difference is a temperature difference between a temperature of the first heating zone at a time when the second heating zone reaches the second setting temperature and the first setting temperature.
