Title: Transfer material separator for image forming device
Inventor: SHIBAYAMA TETSUHIRO
IPC: G03G15/14
Filed: 1986-06-18
Abstract: PURPOSE:To improve sepn. function by a separator using specific materials. CONSTITUTION:The separator is in contact with a transfer charger through a member of which the shape and volume change according to humidity. Plastics having large water absorptivity, for example, polyamide, cellulose, PVA, olefin- vinyl alcohol copolymer, etc., are used as a moisture responsive member. The moisture responsive member swells and the electrostatic charge removing stylus moves in the direction parting from the transfer charger in the case of a high moisture state if the position and bias voltage of the electrostatic charge removing stylus are preliminarily so determined as to meet low-humidity environment. The corona discharge for sepn. by the charge removing stylus is, therefore, not affected and the effective sepn. is executed even if the charge applied to the transfer material tends to diffuse by the decreasing resistance of the transfer material.
