It is intended to provide a method for immobilizing, onto a column carrier, a compound having a sulfo group or a compound to which a sulfo group can be added. The method comprises immobilizing the compound onto the column carrier using a linker comprising: a sulfo group-binding group capable of forming a bond with the sulfo group in the compound; and a carrier-binding group capable of forming a bond with a group present on the surface of the column carrier.

A semiconductor temperature detecting circuit use semiconductor temperature sensors each comprising bipolar transistors connected in a Darlington connection to provide a semiconductor temperature detecting circuit capable of automatically compensating for variations in fabrication of a reference voltage for comparing outputs of temperature sensors. The semiconductor temperature detecting circuit includes a first and a second semiconductor temperature sensor each having bipolar transistors connected in Darlington connection and respectively receiving different constant currents (I and nxI). Temperature detected is based on a corresponding relationship between a ratio of output voltages of the first and the second semiconductor temperature sensors and the temperature.

A pressure-fixable toner comprising a combination of a compound A having a hydrocarbon chain and a compound B having an amino group in addition to a hydrocarbon chain is excellent in dispersibility of colorant, pressure fixing characteristic and developing characteristic. Further, an encapsulated pressure-fixable toner comprising a core of the pressure-fixable toner particles and a shell encapsulating the core is also excellent in these properties.

As a developer for developing electrostatic images in electrophotography, electrostatic recording, electrostatic printing, etc., there is employed a developer containing a finely divided silicic acid which is a finely divided silicic acid synthesized by a wet process and has a pH value of 6 to 11 when suspended at a concentration of 4% by weight in distilled water and the developer can be positively charged strongly and uniformly to visualize the negative electrostatic images, giving a high quality image.
摘要:
An apparatus for developing electrostatic latent images includes an applicator for applying a developer, containing a high concentration of developer particles, uniformly over both the image and non-image areas of a latent image bearing surface, and a developing device including a liquid reservoir and an elastic roller including a core shaft, a porous elastic inner layer on the core shaft, and a flexible and permeable sleeve-like net covering the inner layer. Liquid from the reservoir is applied by the roller to the image bearing surface to remove developer particles not attracted thereto by coulomb force to thereby form the developed image. Marginal effect in the developed image is eliminated by making at least one of the inner layer or net electrically conductive.
