Patent number: 9250574Abstract: In a constitution in which a power source exclusively for primary transfer is omitted and a predetermined voltage is generated in an intermediary transfer member by a constant-voltage element, a high power source voltage more than necessary is applied in order to avoid primary transfer defect, so that a transfer member is deteriorated by energization in some cases. By detecting a current flowing into the constant-voltage element, it becomes possible to obtain a minimum power source voltage at which the intermediary transfer member is capable of maintaining a predetermined voltage, so that it is possible to avoid the energization deterioration of the transfer member.Type: GrantFiled: October 3, 2014Date of Patent: February 2, 2016Assignee: CANON KABUSHIKI KAISHAInventors: Tohru Nakaegawa, Masanori Shida
