Abstract
A mixed crystal consists of a first metallophthalocyanine compound selected from metallophthalocyanine compounds having at least one trifluoromethyl group and having a central metal selected from the group consisting of cobalt, nickel and copper, and a second metallophthalocyanine compound selected from metallophthalocyanine compounds optionally having at least one substituent group other than trifluoromethyl group and having a central metal selected from the group consisting of cobalt, nickel and copper. The mixed crystal exhibits a peak at 2θ of 5.9 to 6.4° in X-ray diffractometry.
