An image forming solvent applying device for applying an image forming solvent, for example, water, to a recording material whereby the recording material is immersed in the image forming solvent and bubbles or dust are wiped from the surface of the recording material. The solvent is supplied into a lower guide member which cooperates with an upper guide member to guide the recording material through the solvent. The two guide members each have a plurality of ribs extending obliquely with respect to a direction of movement of the recording material such that the ribs wipe the entire area of the recording material at least once as viewed in a widthwise direction of the recording material perpendicular to its direction of movement as it is conveyed along the ribs.

摘要:
The present invention is to provide an image-receiving material, such as an image-receiving sheet, for electrophotography, which is excellent in smoothness (gloss), touch and sheet passing property and usable for the photography and which is free from adhesion or blocking to each other during the storage. The present electrophotographic image-receiving material comprises a support, and a toner image-receiving layer containing a thermoplastic resin formed on the support. Organic particles having a glass transition temperature or melting point not higher than a fixing temperature at which an image is fixed on said toner image-receiving layer are incorporated into the toner image-receiving layer or a second layer forming the electrophotographic image-receiving sheet other than the toner image-receiving layer on the toner image-receiving layer side of said support. In addition, the center line average height on the surface of the support is 0.01 to 5 μm and a releasing agent selected from the group consisting of silicon compounds, fluorine compounds and waxes is incorporated into the toner image-receiving layer or any additional layer.
