Overview of Committee of Toner Technology <\/strong>
(3rd Subcommittee)<\/strong><\/h2>\n\n\n\n

The current Technical Committe on Toner Technology took over from the former 3rd Subcommittee, which had been active since the society’s founding with the aim of standardizing electrophotography. In 1995, the 3rd subcommittee was established for the purpose of “standardizing development-related technologies” and “planning and holding technical Seminar”. The name was changed in 2006 to the current name.
In addition, since 1998, we have narrowed down our target technologies to “toner-related technologies,” and within this, we have been conducting activities with the main mission of “standardizing toner charge amount measurement.”<\/p>\n\n\n\n

Subcommittee activity policy<\/strong><\/h2>\n\n\n\n

Since the mission of the Committee on Toner Technology is to “standardize toner-related technology,” the basic policies of its activities are as follows.<\/p>\n\n\n\n

\u3000<\/p>\n\n\n\n

1. Standardization of measurements regarding electrophotographic properties of developers
2. Planning and holding technical seminar that will lead to deeper exploration of toner-related technology and industry-academia collaboration
3. Reporting in technical seminars and journals on the knowledge gained through the activities of the Committee on Toner Technology<\/p>\n\n\n\n

1. Standardization of measured values \u200b\u200bof toner charge amount<\/strong><\/p>\n\n\n\n

Four types of standard carriers have been selected and distributed <\/mark><\/a>so that the measured values \u200b\u200bof various toner charge amount measuring devices can be treated as common scale values \u200b\u200bon the triboelectric series.
In addition, in order to confirm the reliability of the charge amount value of the standard carrier, verification measurements of the charge amount value of the standard carrier are periodically performed using a plurality of various measuring devices.<\/p>\n<\/div>\n\n\n\n

2. Planning and holding of toner technical seminar. <\/strong><\/p>\n\n\n\n

Since 2003, we have set a theme of toner-related technology every year and have planned and held a toner technical seminar that gathers lectures on that theme.<\/p>\n\n\n\n
