Electrophotographic toner having two ethylene polymers |
摘要 |
The present invention provides electrophotographic toner which comprises as a principal component a mixture of 20-80 parts by weight of a first ethylene polymer (X) whose weight-average molecular weight (Mw) is at least 200,000 and a second ethylene polymer (Y) whose Z average molecular weight/number-average molecular weight (Mz/Mn) is at least 6 and Mw is not greater than 50,000. According to this invention, electrophotographic toner of wide non-offset range can be obtained and, images of stable quality in a low heat quantity, which have not been attained by the prior art, can be obtained.
