Abstract
The invention provides a getter of high performance capable of immediately absorbing a gas generated in an image forming apparatus, and an image forming apparatus exhibiting little luminance variation with the lapse of time and little luminance fluctuation. It also provides a method for producing a getter at a low temperature not effecting other components and in an arbitrary position in a simple manner with a low cost, thereby being adaptable to various processes. The invention relates to a process for forming a non-evaporative getter by a gas deposition method, and to a method of producing an image forming apparatus provided with an electron source, an image forming member for forming an image by irradiation with an electron beam emitted from the electron source, and a non-evaporative getter in a container, which comprises forming the non-evaporative getter by the above-mentioned process for forming the non-evaporative getter.
