    • A toner comprising a colorant and a binder resin as the essentials, wherein the binder resin contains at least one polyester resin obtained by polycondensation in the presence of at least one titanium-containing catalyst represented by the general formula (I) or (II) and the toner has a volume-mean particle diameter (Dv) of 2.0 to 10.0mum and a ratio of Dv/Dn (number-mean particle diameter) of 1.00 to 1.40: Ti(-X)m(-OH)n (I) O=Ti(-X)p(-OR)q (II) wherein X is a residue derived from a monoalkanolamine or polyalkanolamine having 2 to 12 carbon atoms by the removal of one hydroxylic hydrogen; the other OH groups of the polyalkanolamine bonded to a Ti atom may be each intramolecularly polycondensed with an OH group bonded directly to the Ti atom to form a ring structure or the other OH groups thereof may be each intermolecularly polycondensed with an OH group bonded directly to another Ti atom to form a repeating structure; R is hydrogen or C1-8 alkyl which may contain one to three ether linkages; m is an integer of 1 to 4 and n is an integer of 0 to 3, the sum of m and n being 4; and p is an integer of 1 to 2 and q is an integer of 0 to 1, the sum of p and q being 2.
    • 一种包含着色剂和粘合剂树脂作为必需品的调色剂,其中粘合剂树脂含有至少一种在至少一种由通式(I)或(II)表示的含钛催化剂的存在下缩聚得到的聚酯树脂和 调色剂的体积平均粒径(Dv)为2.0〜10.0μm,Dv / Dn(数均粒径)为1.00〜1.40:Ti(-X)m(-OH)n(I) O = Ti(-X)p(-OR)q(II)其中X是通过除去一个羟基氢而衍生自具有2至12个碳原子的单烷醇胺或聚链烷醇胺的残基; 与Ti原子结合的聚链烷醇胺的其它OH基可以分别与直接与Ti原子键合的OH基分子内缩聚以形成环结构,或者其它OH基可以分别与直接键合到OH基上的OH基团进行缩聚 另一Ti原子形成重复结构; R是氢或可以含有一至三个醚键的C 1-8烷基; m为1〜4的整数,n为0〜3的整数,m和n的和为4; p为1〜2的整数,q为0〜1的整数,p和q的和为2。
