IPC: H01H11/06
Filed: 1987-04-15
Abstract: PURPOSE:To make the extent of pressurizing force to be added to a support plate at the time of caulking as small as possible without entailing any drop in working speed by inserting a shank of a contact material with a square columnar head part into space between each side face and the inner surface of a through hole so as to have the same clearance, bringing the head part into contact with the support plate, and caulking the contact material to the whole circumference of a peripheral edge of the through hole of the support plate. CONSTITUTION:A distance X between face-to-face opposite sides of a through hole 5 is some what larger than width (x) of a shank 2, before being caulked, of a contact material 1, while a distance Y between other sets of opposite sides of the through hole 5 is set to be larger than length (y) of the shank 2. The opposed one side (a) of a head part 3 is set at one and the same one surface with the side of the opposed one set of a set of the shank 2, while the other side (b) is set as a square column projected as forming a step part equal to both sides from the other side (b) of the shank 2. When length (y) at the side of the other side (b) forming this step part is made larger than length in an (x) direction of the head part 3, a step part area is enlargeable even if step part width is the same, so that pressure per unit area received by a support plate at the time of caulking comes small, thus deformation to be given to the support plate 4 can be made smaller.

Title: Electrostatic charge image developer
Inventor: SHIRASE AKIZO
IPC: G03G9/113
Filed: 1993-04-20
Abstract: PURPOSE:To obtain a developer showing small dependence of charges on environment, good developing property and transfer property, high hardness and good durability and causing no cleaning fault by using a coated carrier the coating layer of which contains hydrophilic silica with specified hydrophobicity degree. CONSTITUTION:This developer is a negative charge developer using a carrier consisting of magnetic particles coated with acryl polymer and using such a coated carrier the coating layer of which contains hydrophilic silica with <20 hydrophobicity degree. If the hydrophobicity is >=20, the adsorption performance for a water molecule is not enough so that the effect to decrease the environmental dependence of the charge amt. is not enough. Since hydrophilic and weak- negative electrifying silica is included in the coating layer of the carrier, the carrier adsorbs water as well as the toner at high humidity and the electrification order shifts to the positive side. Thereby, electrification order of the toner and the carrier does not change so that certain amt. of charge can be maintained without depending on the environmental humidity. Thus, good developing property and transfer property is obtd.
