The release agent is internally added to the toner at 1 to 3wt.% per 100wt.% binder and is externally added thereto at 0.5 to 1wt.% ratio per 100wt.% toner. The above- mentioned release agent, etc., may be formed to particles of desired grain sizes and may then be added to the toner at the time of the external addition.
