IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD

An image forming apparatus includes a first toner image forming unit, a second toner image forming unit, and a transfer section. The first toner image forming unit forms a first toner image with use of a first toner. The first toner has a complex viscosity that falls within a range from 625 Pascal-seconds to 3860 Pascal-seconds, both inclusive, at a temperature of 100 degrees centigrade. The second toner image forming unit forms a second toner image with use of a second toner. The transfer section transfers the first toner image onto a print medium, and transfers the second toner image onto the print medium in a region that overlaps a portion or all of a region where the first toner image has been transferred. The print medium includes a polymer compound. 本发明的图像形成装置具备：第一色粉像形成部，使用第一色粉形成第一色粉像，第一色粉在100℃下的复数黏度大于等于625Pa·s且小于等于3860Pa·s；第二色粉像形成部，使用第二色粉形成第二色粉像；以及转印部，在使第一色粉像转印至含有高分子化合物的介质上之后，在与转印有第一色粉像的区域中的至少一部分重叠的区域中，使第二色粉像转印至介质上。
