Summary:The invention relates to a heater including a plurality of heat generating members, a fixing device, and an image forming apparatus. The heater includes: a substrate; a first heat generating member; a second heat-generating member having a length substantially the same as that of the first heat-generating member in the longitudinal direction; a third heat generating member having a length shorter than lengths of the first heat generating member and the second heat generating member in the longitudinal direction; and a fourth heat-generating member having a length shorter than that of the third heat-generating member in the longitudinal direction, in which the first heat-generating member, the second heat-generating member, the third heat-generating member, and the fourth heat-generating member are disposed on the substrate. 本发明涉及包括多个发热构件的加热器、定影装置以及图像形成装置。加热器包括：基板；第一发热构件；第二发热构件，在纵向方向上该第二发热构件的长度与第一发热构件的长度基本相同；第三发热构件，在纵向方向上该第三发热构件的长度比第一发热构件和第二发热构件的长度短；以及第四发热构件，在纵向方向上该第四发热构件的长度比第三发热构件的长度短，其中第一发热构件、第二发热构件、第三发热构件和第
