Hydroxygallium porphyrazine derivative mixture and electrophotographic photoconductor

A hydroxygallium porphyrazine derivative mixture comprising:

• a plurality of different hydroxygallium porphyrazine derivatives each represented by the following General Formula (B-21):
• where A, B, C and D each independently represent a group selected from the group consisting of an unsubstituted benzo group;
• a benzo group which may have as a substituent a halogen atom, an alkyl group, a hydroxyl group or a benzo group;
• an unsubstituted pyrido group;
• and a pyrido group which may have a substituent a nitro group, a halogen atom, an alkyl group, an alkoxy group, a hydroxyl group or a benzo group.

An electrophotographic photoconductor comprising:

• an electrically conductive substrate;
• and
• a photoconductive layer laid on the electrically conductive substrate,
• wherein the photoconductive layer comprises a hydroxygallium porphyrazine derivative mixture including a plurality of different hydroxygallium porphyrazine derivatives each represented by the following General Formula (B-21):
• where A, B, C and D each independently represent a group selected from the group consisting of:
• an unsubstituted benzo group;
• a benzo group which may have as a substituent a halogen atom, an alkyl group, a hydroxyl group or a benzo group;
• an unsubstituted pyrido group;
• and a pyrido group which may have as a substituent a nitro group, a halogen atom, an alkyl group, an alkoxy group, a hydroxyl group or a benzo group.
