Abstract
A printer with sheet preheating in which toner applied to a toner ribbon is heat-transferred onto a heat adhesive recording sheet, wherein: a heating member heats the recording sheet at a temperature within the range of predetermined temperatures before the heat transfer is provided. Accordingly, the heat adhesiveness of the recording sheet can be substantially constant regardless of the environment of circumferential temperature, and the variation in sensitivities due to the difference in environment to be used and the difference in the order of transfer can be reduced.
Claims18
A printer with sheet preheating in which toner applied to a toner ribbon is heat-transferred onto a transfer surface of a heat adhesive recording sheet, comprising:
- heat transfer means which heats the toner ribbon and the heat adhesive recording sheet, which are superposed, and which carries out the heat transfer;
- and
- heating means which heats the recording sheet at a temperature within a range of predetermined temperatures before said heat transfer means effects the heat transfer of the toner to the transfer surface of the adhesive recording sheet, wherein said heating means is a pinch roller in which a heater is built.
A printer with sheet preheating in which toner having a first color applied to a toner ribbon is heat-transferred onto a transfer surface of a heat adhesive recording sheet and toner having a second color which is different from the first color applied to the toner ribbon is heat-transferred onto the toner having the first color which has been transferred onto the heat adhesive recording sheet, and
- a heating means for heating the recording sheet at a temperature within a range of from above 60.degree. C. to below 140.degree. C. before the toner is heat transferred onto the transfer surface of the recording sheet.
A printer with sheet preheating in which toner having a first color applied to a toner ribbon is heat-transferred onto a transfer surface of a heat adhesive recording sheet and toner having a second color which is different from the first color applied to the toner ribbon is heat-transferred onto the toner having the first color which has been transferred onto the heat adhesive recording sheet, comprising:
- heat transfer means which heats the toner ribbon and the heat adhesive recording sheet, which are superposed, and which carries out the heat transfer;
- and
- heating means which heats the recording sheet at a temperature within a range of from above 60.degree. C. to below 140.degree. C. before said heat transfer means effects the heat transfer of the toner to the transfer surface of the heat adhesive recording sheet.
A printer with sheet preheating in which toner having a first color applied to a toner ribbon is heat-transferred onto a transfer surface of a heat adhesive recording sheet and toner having a second color which is different from the first color applied to the toner ribbon is heat-transferred onto the toner having the first color which has been transferred onto the heat adhesive recording sheet, and
- a heating means for heating the recording sheet at a temperature within a range of from above 70.degree. C. to below 120.degree. C. before the toner is heat transferred onto the transfer surface of the recording sheet.
