摘要:
A developing apparatus develops a latent image formed on a latent image carrying body with a developer. The developing apparatus includes a developing unit having a means for supplying the developer to the latent image carrying body to develop the latent image on the latent image carrying body and a developer housing for accommodating the developer. A developer storage box stores the developer which is to be supplied to the developing unit. The developer storage box is detachably mounted on the developing unit and has a volume substantially the same as a volume of the developer which can be accommodated in the developer case of the developing unit. The developer in developer storage box is supplied to the developing unit.

An electrostatic recording system using a dielectric belt for conducting electrification of a sheet of paper and a transfer belt so that the sheet of paper is not wound and caught by a photoconductor drum, and a transfer voltage can be lowered so as to smoothly separate the sheet of paper from a transfer belt. The electrostatic recording system applies a voltage to only the dielectric belt at a stage before the sheet of paper 3 is attracted to the dielectric belt 10 and applies voltage to the sheet of paper 3 conveyed to the dielectric belt, and to the dielectric belt 10 while the sheet of paper and the belt are mutually superposed.

In a color toner for forming an image, comprising at least a binder resin and a colorant, light-absorbing fine composite particles comprising core particles and at least two coating layers having different refractive indexes laminated on the surface of the core particles or other IR-absorbing compounds such as an azulene compound having a specific structure are used as an infrared absorbing compound. The color toner is used in an electrophotographic color image forming apparatus using a photofixing system for fixing a toner image.

It is an exemplified object of the present invention to provide a developer, a development device and its elements, and an image-forming device that can more stably form a high-quality image by a relatively inexpensive and easy means. A noncontact-type development method according to the present invention utilizes a nonmagnetic and single component toner having a volume average particle diameter D (&mgr;m) and an average specific charge q/m (&mgr;C/g), a development roller having a ten-point average surface roughness Rz (&mgr;m), and a blade keeping in contact with the development roller at a blade line pressure Pb (gf/cm). In order to stably form a uniform toner layer dt (&mgr;m) on the development roller, the following relationship is to be met: dt=1.8×{q/m×Rz/(Pb−1)}½×D±0.25 D, and 1.5 D≦dt≦3.5 D.
摘要:
A refining furnace used for vacuum refining has a sealing cover mounted on the refining furnace so as to cover the furnace throat of the refining furnace and to be in close contact with a sealing flange (10) formed on the refining furnace. The adhesion of metal and slag to the sealing flange is prevented without using any flange cover. A sealing flange (10) is formed on the outer surface of the refining furnace (1) at a position on a conical part (8) extending between the furnace throat (9) and a straight body part or on the straight body part. A slag-stopping dummy flange (11) is formed on the outer surface of the refining furnace (1) at a position between a furnace throat (9) and the sealing flange (10). The slag-stopping dummy flange (11) has an outer circumference lying on the inner side of the inner circumference of a sealing cover (4) and on the outer side of the inner circumference of a lower end part of a dust collecting hood for atmospheric refining.
摘要:
A color toner for electrophotography having excellent fixability and void resistance is capable of forming a high-quality image. The color toner for electrophotography comprises a binder resin and is a magenta toner, and used in combination with at least any of yellow toner and cyan toner. The storage modulus (G′100) (100° C.) of the binder resin is (1/1.1) to (1/10) times the storage modulus (G′100) (100° C.) of a binder resin contained in the yellow toner and the cyan toner. In addition, the color toner for electrophotography comprises a binder resin, C.I. pigment Violet 19, and an infrared absorbent. The color toner is a magenta toner used in combination with at least any of an yellow toner and a cyan toner. The content of the infrared absorbent in the magenta toner is higher than the content of an infrared absorbent in the yellow toner and the cyan toner.
