Abstract
This invention relates to a developer storage and delivery system for liquid electrophotography containing: a) a container having an open end; b) a developer inside said container wherein said developer has a viscosity greater than 10 pascal second; and c) a heater near said open end wherein said heater lower the viscosity of said developer to less than 0.01 pascal second.
Claims11
A developer storage and delivery system for liquid electrophotography comprising:
- a. a container having an open end;
- b. a phase change developer inside said container wherein said phase change developer has a melting point of at least 22° C.;
- and
- c. a heater near said open end wherein said heater melts the top surface of said phase change developer;
- the heater lowering the viscosity of said developer so that heated developer may move towards said open end.
A developer storage and delivery system for effecting liquid electrophotography from a phase change developer source comprising:
- b) a container having a dispensing end;
- c) a phase change developer inside said container wherein said phase change developer has a melting point of at least 22° C.;
- and
- a. a heater to heat at least a surface of the phase change developer in mass transport relationship to the dispensing end;
- the heater lowering the viscosity of said developer so that heated developer may move towards said dispensing end.
A developer storage and delivery system for effecting liquid electrophotography from a phase change developer source comprising:
- d) a container having a dispensing end;
- e) a phase change developer inside said container wherein said phase change developer has a melting point of at least 22° C.;
- and
- a heater to heat at least a surface of the phase change developer in mass transport relationship to the dispensing end, wherein said phase change developer comprises a crystallizing polymeric binder resin derived from a polymerizable monomer selected from the group consisting of hexacontanyl (meth)acrylate, pentacosanyl (meth)acrylate, behenyl (meth)acrylate, octadecyl (meth)acrylate, hexyldecyl acrylate, tetradecyl acrylate, and amino functional silicones.
A developer storage and delivery system for effecting liquid electrophotography from a phase change developer source comprising:
- f) a container having a dispensing end;
- g) a phase change developer inside said container wherein said phase change developer has a melting point of at least 22° C.;
- and
- a heater to heat at least a surface of the phase change developer in mass transport relationship to the dispensing end, wherein said phase change developer comprises an organosol having a graft stabilizer derived from a polymerizable monomer selected form the group consisting of hexacontanyl (meth)acrylate, pentacosanyl (meth)acrylate, behenyl (meth)acrylate, octadecyl (meth)acrylate, hexyldecyl acrylate, tetradecyl acrylate, and amino functional silicones.
A developer storage and delivery system for liquid electrophotography comprising:
- a) a container having an open end;
- b) a developer inside said container wherein said developer has a viscosity greater than 10 pascal second;
- and
- c) a heater to lower the viscosity of said developer to less than 0.01 pascal second so that heated developer may move towards said open end.
