Title: Image forming device
Inventor: SUZUKI TAKASHI
IPC: G03B27/72
Filed: 1987-09-25
Abstract: PURPOSE:To improve picture quality by setting a period from the time when image exposure starts and the time when uniform exposure starts, whichever is earlier, to the time when the image exposure ends and the time when said uniform exposure ends, whichever is later, less than 2min. CONSTITUTION:With lighting beams emitted from a halogen lamp 202, their heat ray wavelength area is removed by a heat ray reflecting filter 220 and a hot-wire absorbing filter 230, and the residual beams irradiate an original 260. Its erecting unmagnified image is formed as a latent image on the surface of a photosensitive member 010 arranged on an exposure 130. Since beams projected on the original develop color close to the image of the original, they are corrected in accordance with the sensitivity spectral distribution of the photosensitive member 010. The subtle adjustment that a main filter 121d alone cannot correct is performed by three types of auxiliary filters. They can freely control the amount that exposing beams block an optical path by external operation, therefore tone can be for readily adjusted.
