Images formed by a liquid are transferred onto both sides of a sheet-like
recording medium without the liquid running on or penetrating into the recording
medium. A layer of absorbing powder is formed on an intermediate transfer member.
The liquid is applied to the powder layer formed on the intermediate transfer member
so as to form a first visible image. The first visible image is transferred onto
the front side of the recording medium. Thereafter, another layer of the absorbing
powder is formed on the intermediate transfer member, and the liquid is applied
to the powder layer so as to form a second visible image. The second visible image
is transferred onto the back side of the recording medium.
