Transfer sheet-carrying member and image forming apparatus

摘要

A transfer sheet-carrying member for use in a transfer-type electrophotographic image forming apparatus is characterized by having a surface sheet showing a downwardly convex current-voltage characteristic across its thickness such that when a first test current I10 is passed at an applied voltage of 10 volts, a second test current I50 is passed at an applied voltage of 50 volts and a third test current I4000 is passed at an applied voltage of 4000 volts, the current-voltage characteristic satisfies the relationships of: I50<5xI10 and I50
