Abstract: An antiallergen filter of the present invention is characterized in that a water-insoluble high-molecular weight anti-allergenic agent having a phenolic hydroxyl group and a moisture-absorbing material are carried on a filter. Because of using the water-insoluble high-molecular weight substance as an anti-allergenic agent, the antiallergen filter of the present invention is free from a problem that the anti-allergenic agent flows and drops or is detached from the filter due to moisture in the atmosphere, etc. even in a highly humid environment or the like. Further, since the moisture-absorbing material is carried on the filter, moisture that the anti-allergenic agent requires for adsorbing and capturing an allergen and inactivating its allergic activity can be effectively retained on the filter. Thus, the antiallergen filter of the present invention can effectively exert its anti-allergenic effect over a prolonged period of time.

Abstract: The present invention can provide an electrophotographic apparatus and electrophotographic method which are less affected by dot gain, can realize smooth gray scale expression, are high in gray scale reproducibility, and are hard to generate moire. In an embodiment of the present invention, a continuous tone image is binarized by using the frequency modulation screening, to form a latent image free from the generation of moire and high in relative resolution. The latent image thus formed is developed using a liquid developer, to form a thin toner layer, for forming a toner image less in the generation of mechanical and optical dot gain.

Abstract: An electrographic printing apparatus and method obtain high-quality images without the occurrence of transfer nonuniformity when toner images are transferred from a latent image carrier to an intermediate transfer medium. The apparatus and method record a toner image present on the latent image carrier by transferring and fixing the toner image to a recording medium via the intermediate transfer medium having an elastic layer on a surface thereof. The printing apparatus has a tensile spring for pressing the intermediate transfer medium against the latent image carrier, and the pressing force of the tensile spring is set so that the straightness in the width direction on the surface of the elastic layer is not larger than the height of the toner image.

Abstract: A method for printing on a metal item includes the step of successively forming a plurality of electrostatic latent images based on print information color-separated into yellow, magenta, cyan and black, on a photosensitive drum. The electrostatic latent images are successively developed by toners of different colors corresponding to the color-separated print information. A multicolor toner image is formed on an intermediate transfer medium having a cushion layer thereon by successively repeating a process in which the toner images are transferred to the intermediate transfer medium in layers. The multicolor toner image is transferred onto a surface of a metal item. Thereafter, the multicolor toner image is fixed on the surface of the metal item.
