PROBLEM TO BE SOLVED: To provide a toner for developing an electrostatic charge image, which shows excellent anti-blocking properties under high-temperature/high-humidity conditions and an excellent low-temperature fixability and comprises a polyester resin based toner binder. SOLUTION: The toner for developing an electrostatic charge image comprises at least one amorphous polyester resin (A) and a crystalline polyester (B), wherein the polyester resin is formed in the presence of at least one titanium-containing catalyst (a) represented by the general formula (I) or (II): Ti(-X)m(-OH)n (I); and O=Ti(-X)p(-OR)q (II), wherein X is a residue formed by removing H from one OH group in a 2-12C (poly)alkanolamine; R is H or a 1-8C alkyl group which may contain 1-3 ether bonds; (m) is 1-4 and (n) is 0-3, provided that the sum total of (m) and (n) is 4; and (p) is 1-2 and (q) is 0-1, provided that the sum total of (p) and (q) is 2 ((m), (n), (p) and (q) independently represent an integer).
