    摘要： The present invention intends to provide a simple process for preparing a triarylamine dimer without using any expensive chemicals, the process being able to achieve high reaction yield and being advantageous to be carried out on an industrial scale. The present invention provides a process for preparing a triarylamine dimer (I) using the Ullmann reaction represented by the scheme: wherein X represents a halogen atom, R 1 and R 2 represent independently a hydrogen atom, an alkyl group, an alkoxy group or a halogen atom, Ar represents a phenylene group, or a naphthylene group, characterized in that the reaction accelerator is polyethylene glycol or di- or monoalkyl ether of polyethylene glycol.

    摘要： A method for manufacturing a charge control agent comprising steps of:

    an initiative chelating step by reacting with a monoazo compound represented by the following chemical formula [1]
    (in the chemical formula [1], -Ar 1 - and -Ar 2 - are aromatic groups) and a metal chelating agent to prepare an azo-type metal complex salt intermediate;
    a subsequent ion-exchanging step by reacting with the azo-type metal complex salt intermediate and an ammonium counter ion forming agent including an inorganic ammonium salt and aqueous ammonia to prepare an azo-type metal complex salt having an ammonium ion of a counter ion represented by the following chemical formula [2]
    (in the chemical formula [2], -Ar 1 - and -Ar 2 - are the same as the chemical formula [1]; M is a trivalent metal; B + is a cation except an ammonium ion; n is from 0.70 to 1.00).
