Abstract

Abstract An image recording apparatus which can provide an output visible image on an ordinary sheet. The apparatus uses a photosensitive recording medium whose surface is provided with microcapsules encapsulating therein a chromogenic material or dye precursor. Developer material particles are supplied over one of the photosensitive recording medium and the ordinary sheet for generating a chromogenic reaction with the dye precursor.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 228 words
An image recording apparatus for recording an output image on a sheet medium, the sheet medium being any ordinary copying sheet material, the output image corresponding to an image of an original, said original containing first and second images, the apparatus using a photosensitive recording medium having a surface which carries microcapsules encapsulating therein a chromogenic material, the apparatus comprising: exposure unit means for exposing to light said photosensitive recording medium for forming a latent image corresponding to said first image on the photosensitive recording medium; supplying means for supplying developer material particles which undergo a chromogenic reaction with the chromogenic material, the supplying means supplying said developer material particles to the ordinary copying sheet material for recording said first image, said developer material particles supplying means including a photosensitive drum; pressure developing unit means disposed downstream of the exposure unit for generating the chromogenic reaction between the chromogenic material and said developer material particles to provide said first image on the ordinary copying sheet material; and means for supplying toner particles onto said ordinary copying sheet for recording said second image thereon, said toner particles supplying means comprising: a photosensitive drum; a toner image forming means for forming a toner image corresponding to the second image onto the photosensitive drum; and a means for transferring the toner image on the photosensitive drum onto said ordinary copying sheet.
Claim 2
Dependent Claim 228 words
An image recording apparatus for recording an output image on a sheet medium, the sheet medium being any ordinary copying sheet material, the output image corresponding to an image of an original, said original containing first and second images, the apparatus using a photosensitive recording medium having a surface which carries microcapsules encapsulating therein a chromogenic material, the apparatus comprising: exposure unit means for exposing to light said photosensitive recording medium for forming a latent image corresponding to said first image on the photosensitive recording medium; supplying means for supplying developer material particles which undergo a chromogenic reaction with the chromogenic material, the supplying means supplying said developer material particles to the ordinary copying sheet material for recording said first image, said developer material particles supplying means including a photosensitive drum; pressure developing unit means disposed downstream of the exposure unit for generating the chromogenic reaction between the chromogenic material and said developer material particles to provide said first image on the ordinary copying sheet material; and means for supplying toner particles onto said ordinary copying sheet for recording said second image thereon, said toner particles supplying means comprising: a photosensitive drum; a toner image forming means for forming a toner image corresponding to the second image onto the photosensitive drum; and a means for transferring the toner image on the photosensitive drum onto said ordinary copying sheet.
Claim 3
Dependent Claim 25 words
The image recording apparatus as defined in claim 1, wherein the first image is a picture image and the second image is a character image.
Claim 4
Dependent Claim 42 words
The image recording apparatus as defined in claim 1 further comprising means for forming a developer material particle image corresponding to first image, said toner image forming means being operated during an inoperative state of the developer material particle image forming means.
Claim 5
Dependent Claim 32 words
The image recording apparatus as defined in claim 3 further comprising a thermal fixing unit disposed downstream of the pressure developing unit for fixing the output image on the ordinary copying sheet.
