TRANSFER ROLLER CLEANING DEVICE FOR ELECTRO-PHOTOGRAPHIC PRINTER

摘要

PURPOSE: A transfer roller cleaning device for an electro-photographic is provide to effectively clean an alien material of transfer roller by inhibiting a clearance that formed between trans roller and cleaning roller. CONSTITUTION: A cleaning roller(140) comprises a rotating shaft(141) consisting of a metal and a rubber(142) wrapping the periphery of rotating shaft(141). The rubber is elastically deformed by adhering cleaning roller(140) closely to the transfer roller(120). A heater(122) is positioned into the inside of the transfer roller(120) in order to stand heat. To remove an alien material from the transfer roller(120), the rubber(120) is higher than the transfer roller(120). The rubber(120) consisted of a silicon and a fluorine. The toner image(320) is carried at the transfer roller of photosensitized medium(100). The rotating shaft(141) is supported by a supporting part(151). A cam part(153) pushes to the supporting part(151) toward the anti direction of transfer roller(151).
