Title: Electrostatic charge image developing toner
IPC: B01J2/22
Filed: 1992-03-11
Abstract: PURPOSE:To improve the working environment of the production of a toner, and to obtain a toner showing stable fogging and having good splashing state of the toner and little change in the density of copied picture images in continuous copying without deteriorating the dispersibility of the coloring agent in the toner under any use environment by including a resin and a granulated coloring agent in the toner. CONSTITUTION:Any well-known resin suitable for an electrostatic charge image developing toner may be used as the resin component. Any powder coloring agent may be used for the source material of the granulated coloring agent. The powder coloring agent is compacted under such load properly determined to obtain 1.2-2.0 bulk density ratio and more preferably 1.2-1.8 bulk density ratio before and after granulating. If the bulk density ratio is <1.2, splashing of the coloring agent increases during handling the coloring agent and the bulk volume of the source material increases. This makes shearing difficult during kneading, and dispersibility of the coloring agent in the toner becomes bad to deteriorate the toner performance. If the bulk density ratio is >2.0, aggregation of the coloring agent increases and enough dispersibility is not obtd. during kneading and deteriorates the toner performance.

Filed: 1978-05-06
Abstract: PURPOSE: To obtain uniform thickness of metal part crystallized by electrodeposition by forming small circular holes other than a hole of the shape of part in a photosensitive and chemical resistant film coated on a base plate.  
     CONSTITUTION: The photosensitive and chemical resistant film 12 is coated on the matrix metal base plate 11, exposed to light by photographic processing, and then removed by dissolution by a developing solution to form the hole 13 of the shape of part. At the same time, a plural number of small circular holes 14 in such a way that ratio of the base plate exposed area of the hole 13 portion to the insulating area of the photosensitive and chemical resistant film 12 is almost uniform. Thus, current line in electrodeposition process is distributed even into the small circular hole 14, whereby the current density in a portion of a broad exposure width becomes similar to that in a portion of a shallow exposure width and thus the thickness of crystallized metal part becomes uniform. In addition, electrodeposition stress becomes almost constant and thus the control of electrodeposition stress can be made easier by electrodeposition conditions. Furthermore, no secondary processing such as buffing, etc., is required because of uniform crystallization of metal part.
