Summary:The invention relates to a heating device and an image forming device, and aims to suppress defects caused by uneven temperature of a heating part due to heat generation of a conductor pattern. The heating device comprises an endless fixing belt (20), a pressure roller (21) which is in contact with the fixing belt (20) to form a fixing nip (N), a long heater (22) which heats the fixing belt (20), and pressure mechanisms (80A) and (80B) which are used for forming the fixing nip (N) between the fixing belt (20) and the pressure roller (21) for the fixing belt (20) or the pressure roller. The pressure mechanisms (80A) and (80B) enable the pressure applied to the side where the amount of heat generated in the longitudinal direction of the heater (22) is large to be relatively smaller than the pressure applied to the side where the amount of heat generated in the longitudinal direction is small. 本发明涉及的加热装置及图像形成装置目的在于抑制因导体图案的发热引起的加热部件的温度的不均所导致的不良情况。该加热装置包括环状的定影带(20)、与定影带(20)接触形成定影夹持部(N)的加压辊(21)、加热定影带(20)的长条状的加热器(22
