Title: Binary developer
Inventor: KITAHATA YASUO
IPC: G03G9/113
Filed: 1987-07-25
Abstract: PURPOSE:To prevent fogging even when a developer is used for a long time and a carrier coating agent peels off by coating the surface of a carrier with a coating agent made of a material reducing a quantity to be triboelectrified on the surface of a toner. CONSTITUTION:The coating agent to be used for coating the surface of the carrier is made of a material reducing a quantity to be triboelectrified by friction between the toner and the noncoated carrier. As a result, the triboelectrification quantity on the toner is kept smaller than a quantity triboelectrified by friction with the noncoated carrier until the carrier coating agent begins to peel, and when it begins to peel, since the surface of the toner comes into friction with the surface of the noncoated carrier, the triboelectrification quantity increases more than that before the peeling, thus permitting the triboelectrification quantity to tend to increase even when it is used for a long time, and fog not to occur on an image.

Title: Electric field ionizing ion source
Inventor: TAKIZAWA MASAAKI
IPC: H01J49/16
Filed: 1988-07-26
Abstract: PURPOSE:To obtain a stable electric field ionizing ion source having high luminance by using neon gas as ion source gas. CONSTITUTION:Neon gas is used as ion source gas. As for an electric field to be ionized, a following inequality is set: H2<Ar<Ne<He. Relation of each boiling point of the elements is represented by an inequality: He<H2<Ne<Ar. In order to take out a high ion current, it is effective to cool the ion source gas down near the boiling point so as to thicken molecular density. Ne, Ar and H2 are desirable for the ion source gas, and He and Ne are more desirable because the ion beam current is liable to be unstable due to a residual gas component and yet discharge is likely to be generated when the electric field to be ionized is low. From the point of view of unstability of the ion current, Ne is superior to He. Therefore, a stable electric field ionizing ion source having high luminance can be obtained.

CONSTITUTION:An InGaAsP intermediate layer is divided into at least a first n-InGaAsP intermediate layer 4 and a second n-InGaAsP intermediate layer 4'. Carriers larger in an ionization factor in the second n-InGaAsP intermediate layer 4' adjacent to an n-InP avalanche layer 5 are set identical with InP. In the case of InP, an ionization factor beta of hole carriers is larger than an ionization factor alpha of electron carriers. A relation alpha>beta is defined centrarily in the case of InGaAs. InGaAs composition of alpha>beta and that of beta>alpha exist in InGaAsP with a forbidden band width Eg which is an intermediate value of their widths between InP and InGaAs. when the InGaAsP of Eg>=1.14eV is formed as the second intermediate layer 4' and even if a hetero-electric field is high (e.g., E>250KV/cm) enough to generate avalanche multiplication in the InGaAsP, no noise occurs because of beta>alpha similarly with InP.
