Title: Image forming method
Inventor: HAMADA JUNICHI
IPC: G03G15/01
Filed: 1984-11-07
Abstract: PURPOSE:To reproduce sharply an image consisting of chromatic and achromatic colors with high accuracy by using the 1st electrostatic charge image of a negative formed on an image carrying body as the 1st image information and the positive and negative ion currents passing through an ion current control screen as the 2nd image information. CONSTITUTION:The entire surface of a photosensitive screen 17 is electrostatically charged to negative over the entire surface and a photosensitive body 1 is subjected to secondary negative electrostatic charge in succession to the primary positive electrostatic charge over the entire surface. Said body is subjected to image exposure by the light from an original 44. A dichroic mirror 44 reflects the light of an R component and allows the transmission of B and G components. The surface potential of the body 1 is the image information of the negative. The positive particles pass selectively through the negative electrostatic charge region of the screen 17 and the negative particles pass through the region where the screen is not charged to negative when the positive and negative ion particles are projected from a charge particle source 19. The charge of the positive or negative polarity is selectively left on an insulating layer 57 and the electrostatic latent image separated with the positive chromatic levels G, B, C and negative chromatic levels Y, R, M on both sides of the achromatic levels (w), (b) is formed. The optional chromatic color is thus formed to a visible image by development.

IPC: G03G9/083
Filed: 1992-09-03
Abstract: PURPOSE:To obtain a picture image having a stable triboelectric charge quantity and a high quality even in the high humidity circumstances by strongly fixing fine particles having the static charge characteristic of the same polarity as a magnetic toner on the surface and weakly fixing fine particles having the static charge characteristic of the reversed polarity to the magnetic toner. CONSTITUTION:In the magnetic toner for electrostatic charge image which is essentially consisting of a binding resin and magnetic powders and constitutes a two-component developer by blending a magnetic carrier therewith, the fine particles having the static charge characteristic of the same polarity as the magnetic toner are strongly fixed on the surface and the fine particles having the static charge characteristic of the reversed polarity to the magnetic toner are weakly fixed. As a strong fixing means, a method where magnetic toners and fine particles are mixed in air flow vortexes using a Henschel mixer is exemplified. A weak fixing means can be done under an ordinary mixing condition. The charge stabilization function of the magnetic toner is secured by the presence of fine particles having the static charge characteristic of the same polarity as the magnetic toner and the flowability of the magnetic toner is secured by the presence of fine particles having the static charge characteristic of the reversed polarity to the magnetic toner.
