摘要:
The present invention discloses a device for regenerating a sheet-like recording medium comprising a means for feeding a printed sheet-like recording medium, a regenerating treatment means having a step for eliminating image formed on said recording medium, a means for discriminating and separating the recording medium whether the treated recording medium is reusable or not and a means for storing the separated reusable recording medium.Further, the present invention discloses, as Examples, regenerating treatment means treating sheet-like recording media printed with following toners or inks with following degrading agent or a color eliminating agent;(i) a toner comprising biodegradable plastics as a constituent ingredient and an enzyme containing liquid as a degrading agent;(ii) a toner comprising photodegradable plastics as a constituent ingredient and an irradiation of a light containing a short wavelength light;(iii) a toner or an ink using a coloring material comprising an electron-donating color-forming organic compound and its developer and a color-eliminating agent; and(iv) a toner or an ink using a coloring material comprising an electron-accepting color-forming organic compound and its developer and a color-eliminating agent.
摘要:
An electrophotographic digital copier capable of identifying a particular color existing in a document image. The copier copies both of a bicolor document and a monocolor document in the same period of time. Even when monocolor documents and bicolor documents are to be copied together, the copier executes monocolor copy processing with the former and bicolor copy processing with the latter automatically.
摘要:
An electrophotographic image developing device includes a fixed rotatable member and a suspended rotatable member reciprocally movable toward and away from the fixed rotatable member. Rotative power from a drive source is transmitted to the suspended rotatable member through a power transmitting unit which includes a coupling capable of absorbing axial misalignment between driver and driven shafts.
