Abstract
The present invention provides a porous body for the absorption of a liquid component contained in an ink image on an ink receiving medium, the porous body including a fiber having a pore structure in the inside, wherein the pore structure satisfies the following requirements (a) and (b), and an inter-fiber void ratio which indicates the volume ratio of a void formed between the each fibers is 40% or more to 80% or less: (a) average pore size/average fiber diameter is 0.2 or less; and (b) an intra-fiber void ratio is 5% or more to 40% or less.
Claims4
An ink jet printing apparatus comprising:
- an ink application apparatus which applies ink onto an ink receiving medium to form an ink image;
- and
- a liquid absorbing member having a porous body which comes into contact with the ink image and absorbs at least a portion of a liquid component from the ink image,
- the porous body comprising a fiber having a pore structure in the inside, wherein
- the pore structure satisfies the following requirements (a) and (b), and
- an inter-fiber void ratio which indicates the volume ratio of a void formed between f the each fibers is 40% or more to 80% or less:
- (a) average pore size/average fiber diameter is 0.2 or less;
- and
- (b) an intra-fiber void ratio is 5% or more to 40% or less.
