An image formation method comprising exposing a photothermographic material
10
having an image-forming layer and a back layer with a light having a wavelength of 700-850 nm and subjecting it to development in a heat development apparatus provided with a preheating section A, a heat development section B and a gradual cooling section C, wherein the photothermographic material
10
has at least one coated layer obtained by applying a coating solution containing 20 weight % or more of an organic solvent, and the heat development section B is provided with heating members
15
on image-forming layer side
10
a
and back layer side
10
b
and transportation rollers only on the image-forming layer side
10
a
with respect to the photothermographic material
10
to be transported in the apparatus. There is provided an image formation method utilizing a photothermographic material, which can form images showing less generation of density unevenness, high contrast and high maximum density without causing physical deformation.
一种图像形成方法,包括使用波长为700-850纳米的光照射具有成像层和背层的光热材料10,并将其置于具有预热部分A、热发展部分B和逐渐冷却部分C的热发展设备中进行开发。其中,光热材料10至少具有一层涂布层,该涂布层是通过涂布溶液制备的,该涂布溶液含有20重量%或更多的有机溶剂,热发展部分B在与将在设备中传输的光热材料10的成像层面10a和背层面10b相对应的仅在成像层面10a上具有加热元件15和传送辊。提供了一种利用光热材料的图像形成方法,该方法可以形成显示较少密度不均匀性、高对比度和高最大密度的图像,而不会引起物理变形。
