Abstract

PROBLEM TO BE SOLVED: To minimize unrecordable parts to be generated due to adherence of dust or the like to the surface of a film between a toner film and a receiver film by furnishing a light absorption layer on the receiver film. SOLUTION: A toner 10 is laminated on the lower surface of a base 11 with a color agent layer 13 via a cushion layer 12. A receiver film 20 is formed by laminating a light absorption layer 23 on the upper surface of a base 21 via a cushion layer 22, and laminating heat adhesive layer on the upper surface thereof. Heat of the light absorption layer 23 by a laser beam from the upside acts to heat the heat adhesive layer 24. When color agent layer 13 is adhered on heated parts of the heat adhesive layer 24, images can be transfer formed desirably. Upon heating the heat adhesive layer 24 through heat of the light absorption layer 23, since the light absorption layer 23 is set on the receiver film 20, a heat conductivity from the light absorption layer 23 to the heat adhesive layer 24 is hot precluded even in the event of dust or the like adhered to the surface of any film between the toner film 10 and the receiver film 20.

Next, the toner film 10 shown in FIGS. 1 and 2 of the transfer type recording systems of the first and second embodiments will be described.
An experiment was conducted to compare the receiver films 20 and 30 with the toner film 40 and the receiver film 50 of the conventional transfer type recording system shown in FIG. Various conditions, experimental methods and results regarding the experiment are described below.

First, a diameter 20 as a substitute for dust or the like is used.
Vacuum was drawn while the μm beads were sandwiched between the toner films 10 and 40 and the receiver films 20, 30 and 50, and the films were brought into close contact. Next, a laser beam (980 nm, 100 m
W), 3 m / s from the toner film 10, 40 side
Was scanned. The sub-scanning pitch was set to 10 μm, and exposure was performed so that no gap was generated.

Thereafter, the receiver films 20, 30,
The toner films 10 and 40 were peeled off from 50, and the diameter of the unrecordable portion around the beads was measured.

As a result, in each of the toner film 10 and the receiver films 20 and 30 shown in FIGS. 1 and 2, the diameter of the unrecordable portion was 400 μm. On the other hand, in the conventional toner film 40 and receiver film 50 shown in FIG.
