摘要：
A heating device for heating a recording sheet includes: a first heater disposed within a heating roller and having a heat distribution characteristic to form a low temperature region in an axially central portion of the heating roller and a high temperature region in each of axially opposite end portions of the heating roller; and a second heater disposed within the heating roller and having a heat distribution characteristic to form a high temperature region in the axially central portion of the heating roller, a low temperature region in each of the opposite end portions of the heating roller, and a second-level high temperature region in each of axially opposite end portions of the high temperature region, the second-level high temperature region being lower in temperature than the high temperature region.
