摘要:
An ink jet recording apparatus is provided with a black head and a plurality of color heads. The black head has a predetermined number of first orifices aligned at predetermined intervals (e.g. 0.0169 mm) in a sub scanning direction (direction in which a print medium travels). The plurality of color heads eject different colored ink drops. Each color head has the predetermined number of second orifices aligned in the sub scanning direction perpendicular to the main scanning direction. The second orifices of adjacent color heads are aligned in a main scanning direction perpendicular to the sub scanning direction.

A method of producing a carbon fiber composite material includes a first step and a second step. The first step includes oxidizing first carbon nanofibers produced by a vapor growth method to obtain second carbon nanofibers having an oxidized surface. The second step includes mixing the second carbon nanofibers into an elastomer, and uniformly dispersing the carbon nanofibers in the elastomer by applying a shear force to obtain the carbon fiber composite material. The second carbon nanofibers obtained by the first step have a surface oxygen concentration measured by X-ray photoelectron spectroscopy (XPS) of 2.6 to 4.6 atm %.
