Image forming apparatus
First Claim
1. An image forming apparatus for forming an image on a transfer medium by pressing the transfer medium against a photosensitive medium having light sensitive microcapsules thereon, the apparatus comprising:
- an illuminating mechanism for illuminating said photosensitive medium; and
exposure means for subjecting a first predetermined region of the photosensitive medium to light representative of the image and a second predetermined region of the photosensitive medium to light nonrepresentative of the image prior to pressing the transfer medium against the photosensitive medium.

Abstract
An image forming apparatus includes a photosensitive medium having light sensitive microcapsules thereon which are pressed against a transfer medium to transfer a latent image from the photosensitive medium to the transfer medium. A pressure developing device is employed which generates a load only during that period when the image is being developed on the receiving medium. The photosensitive medium is contained in a detachable container. A thermal treatment mechanism fixes the images formed on the receiving medium and imparts a glossy finish. An illuminating mechanism illuminates directly or indirectly the photosensitive medium. An exposure mechanism subjects a first predetermined region of the photosensitive medium to light representative of the image and a second predetermined region of the photosensitive medium to light nonrepresentative of the image. The exposure mechanism also subjects the first predetermined region of the photosensitive medium to light having a uniform intensity.

38. An image forming apparatus for forming an image on a transfer medium by pressing the transfer medium against a photosensitive medium having light sensitive mircocapsules thereon, the apparatus comprising:
-
an illuminating mechanism for illuminating said photosensitive medium and including means for filtering and absorbing heat generated by the illuminating mechanism; first means for subjecting a first predetermined region of the photosensitive medium to exposure of light representative of the image; uniform intensity means for subjecting the first predetermined region to a uniform intensity of light; second means for subjecting a second predetermined region of the photosensitive medium to light nonrepresentative of the image; reflecting means for redirecting light which has passed through the photosensitive medium toward said photosensitive medium once again; color temperature filter means for adjusting the color temperature of light traveling towards said photosensitive medium and including a dichroic filter which partially reflects light having a wavelength of at least 500 nanometers; and color adjusting filter means for further adjusting the spectral distribution of light traveling towards said photosensitive medium, said color adjusting filter means including at least one color adjusting filter and at least one transparent glass portion whose optical path lengths are substantially equal.

39. A method for forming an image on a transfer medium by pressing the transfer medium against a photosensitive medium having light sensitive microcapsules thereon in combination with a light source, said method comprising:
-
exposing a first predetermined region of the photosensitive medium to light representative of the image to be formed thereon; and exposing the first predetermined region of the photosensitive medium to light having a uniform intensity prior to pressing the transfer medium against the photosensitive medium. - View Dependent Claims (40)
