Title: Electrophotographic color toner
Inventor: ICHIMURA MASANORI
IPC: G03G9/09
Filed: 1992-11-27
Abstract: PURPOSE:To enable the adequate electrostatic charge of toner particles even under a high humidity environment without being affected by an environmental humidity change by consisting coloring agents of org. pigments which are of a specific value or below in the specific electric conductivity of the extract by ion exchange water. CONSTITUTION:The org. pigments are required to be <=150mus/cm in the specific electric conductivity of the extract obtd. by extracting these pigments with the ion exchange water. The toners are easily affected by the humidity change of the environment and do not exhibit the adequate electrostatic chargeability under the high humidity environment if the specific electric conductivity is larger than 150mus/cm. The org. pigments having <=150mus/cm specific electric conductivity of the extract by the ion exchange water are obtd. by repeating washing with water in a washing stage in the final stage of the synthesis process thereof, then dehydrating the pigments and drying the resulted pigment paste. This process may be made master batchwise by kneading the pigments in the state of wet cake with a part of a binder resin without passing the cake to the drying state after dehydrating in such a case.

Abstract: PROBLEM TO BE SOLVED: To prevent erroneous information from being outputted temporarily from a complementary output by using a current mirror load type amplifier in the preceding stage as a sense amplifier and the amplifier consisting of an NMOS differential circuit and a PMOS latch in the poststage. SOLUTION: The sense amplifier(SA) consisting of NMOS differential Q43, Q44, Q43', Q44' and PMOS current mirror Q41, Q42. Q41', Q42' is provided in the preceding stage, and the amplifier consisting of gate input differential circuits Q48, Q49 and PMOS latches Q46, Q47 is provided in the poststage. Although the current mirror SA is high speed, it isn't as high speed as a cross couple connection load type SA in the poststage. Then, an amplification factor of a load circuit is smaller than the SA cascade connecting two stages of amplifiers in the poststage. Thus, the amplitude of the erroneous information caused from the preceding stage is small, and the delay from the point of time when a word line drive signal is applied to the point of time of an SA output is small also.
