Abstract

An image forming method is disclosed, comprising (a) exposing a recording material comprising on a support an image forming layer containing colored magnetophoretic particles and a photopolymerizable composition to light to perform photocuring and (b) applying a magnetic field to the recording material to migrate the magnetophoretic particles.

Claims

1. An image forming method comprising:

(a) exposing a recording material comprising on a support an image forming layer containing colored magnetophoretic particles, colored non-magnetic particles differing in color from the colored magnetophoretic particles, and a photopolymerizable composition, to light to perform photocuring and

(b) applying a magnetic field to the recording material to migrate the magnetophoretic particles.

2. The image forming method of claim 1, wherein the method comprises:

(i) imagewise exposing the recording material to light to perform photocuring and then

(ii) applying a magnetic field to the recording material to migrate the magnetophoretic particles.

3. The image forming method of claim 1, wherein the method comprises:

(i) imagewise applying a magnetic field to the recording material to migrate the magnetophoretic particles and then

(ii) exposing the recording material to light to perform photocuring.

4. The image forming method of claim 1, wherein the recording material is exposed to a light having plural emission peaks in the wavelength range of 400 to 700 nm.

5. The image forming method of claim 2, wherein the method further comprises

(iii) exposing the recording material overall to the light.

6. The image forming method of claim 1, wherein the magnetophoretic particles comprise white particles or black particles.

7. The image forming method of claim 1, wherein the magnetophoretic particles comprises yellow particles, magenta particles and cyan particles.

8. The image forming method of claim 1, wherein the magnetophoretic particles and the photopolymerizable composition are included in capsules.

9. The image forming method of claim 1, wherein the support has recesses at regular intervals.

10. The image forming method of claim 1, wherein the recording material further comprises a white light-scattering layer.

11. The image forming method of claim 1, wherein the non-magnetic particles are white particles or black particles.

12. The image forming method of claim 11, wherein the non-magnetic particles are white particles.
