摘要：
PROBLEM TO BE SOLVED: To reduce failures such as disconnection, due to contact of a harness in an image forming apparatus, and also to constitute the image forming apparatus so that firing of a resin gear or the like may hardly occur.
SOLUTION: Charging harnesses 142 and 144 as covered conductors are each arranged above a charging bias delivery part 143 as a contact point with a charging roller, and also, above a developing bias delivery part 145 as a contact point between the developing harness 144 and a developing roller. A photoreceptor driving gear 121 that transmits the drive coaxially with the photoreceptor drum, and a developing driving gear 123 that transmits the drive to the developing roller are made to function as drive delivery members. Other drive transmission members 124 to 130 are arranged on the opposite side of the charging harnesses 142 and 144, with respect to the photoreceptor driving gear 121 and the like. Consequently, the failures, such as disconnection, due to the contact of the harness are avoidable. A harness guide 141 holds the charging harnesses 142 and 144, and functions as a partitioning member for avoiding an interference between the harness and the drive transmission means.
