CONSTITUTION:The dry toner composed essentially of the binder resin and the colorant contains the charge controller having an average particle diameter of &lt;=5mum, for example, negative type metal-containing dyes, such as azo type metal complex salts and chromium complex salts, and positive type dyes, such as nigrosine dyes or quaternary ammonium salts. The charge controller may be pulverized and classified into an average particle diameter of &lt;=5mum in advance or in the step of handling raw materials. The binder resin to be used is as follows; styrene resins, polyacrylate resins, polyester resins, polyvinyl chloride resins, epoxy resins, and polyester resins, and the colorant to be used is such as carbon black, monoazo type red dyes, disazo type yellow dyes, quinacridone type magenta pigments, and anthraquinone dyes. As other additives, a polyethylene-fluoroethylene powder and the like are used.</description><language>eng</language><subject>CINEMATOGRAPHY ; ELECTROGRAPHY ; ELECTROPHOTOGRAPHY ; HOLOGRAPHY ; MAGNETOGRAPHY ; PHOTOGRAPHY ; PHYSICS</subject><creationdate>1991</creationdate><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&amp;date=19910705&amp;DB=EPODOC&amp;CC=JP&amp;NR=H03157670A$$EHTML$$P50$$Gepo$$Hfree_for_read</linktohtml><link.rule.ids>230,308,780,885,25564,76547</link.rule.ids><linktorsrc>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&amp;date=19910705&amp;DB=EPODOC&amp;CC=JP&amp;NR=H03157670A$$EView_record_in_European_Patent_Office$$FView_record_in_$$GEuropean_Patent_Office$$Hfree_for_read</linktorsrc></links><search><creatorcontrib>SANO AKIHIRO</creatorcontrib><creatorcontrib>EBIOKA SHIGERU</creatorcontrib><creatorcontrib>KUWABARA HIDEMITSU</creatorcontrib><creatorcontrib>TOTSUKA HIROMI</creatorcontrib><creatorcontrib>MATSUYAMA SHIGEO</creatorcontrib><title>ELECTROPHOTOGRAPHIC DRY TONER</title><description>PURPOSE:To obtain a dry toner superior in fixing strength by adding a specified electrostatic charge controller having a specified average particle diameter internally into a dry toner composed essentially of a binder resin and a colorant.
