A waste liquid tank that holds waste recording liquid is disclosed. In the waste liquid tank, a waste liquid wetting liquid that forms a liquid layer on the surface of the waste recording liquid is placed in the form of a liquid.

Waste liquid tank, liquid ejection device, and image forming apparatus

A disclosed image forming apparatus includes a line-type liquid discharging head including nozzles configured to jet liquid droplets. The nozzles are aligned in a sheet width direction. The line-type liquid discharging head includes plural nozzle rows each including an alignment of a plurality of the nozzles configured to discharge liquid droplets of the same color. A distance Lbetween the nozzle rows is L=T1&#xd7;V, where Tis a liquid transfer amount impregnating time of a standard sheet and Vis a sheet conveying speed.

Image forming apparatus, liquid discharging head, image forming method, recorded matter, and recording liquid

A recording material including paper containing cellulose fibers as the main component, with the elongation percentage of the paper in the cross direction thereof when immersed in water at 20.degree. C. for 1 minute being 1.8 % or less, is produced and recycled. In addition, paper containing cellulose fibers, with the same elongation percentage as mentioned above in the machine direction thereof is also provided.

Recording material, method of producing the same and method of recycling

A method of recycling an image-bearing recording material, at least part of a surface portion having a paper layer which contains cellulose fibers and bears thereon images formed by a thermofusible or thermosoftening ink, includes the steps of causing the image-bearing surface portion of the recording material to hold a water-containing image removal acceleration liquid thereon, and causing the images to adhere to an image releasing member with the application of heat and/or pressure to the images, whereby peeling the images away from the surface portion, with the surface portion of the recording material having a contact angle (cos.theta.) of -0.6 to 0.8 when a liquid with a surface tension of 40 mN/m is placed dropwise on the surface portion of the recording material.

Method of recycling image-deposited recording material, and recording

A thermosensitive recording paper comprising a support sheet and a thermosensitive coloring layer formed thereon, which support sheet comprises needle-leaf tree pulp in an amount ratio of 10 to 50 wt. % of the absolute dry weight of the support sheet, with the maximum length of the fibers in the needle-leaf tree pulp being 4 mm or less.
