  • Publication number: 20240103410
    Abstract: An image forming apparatus includes an image carrier to carry a toner image, intermediate, primary, and secondary transfer members, and a voltage application member. The voltage application member applies a voltage to the image carrier. The secondary transfer member is in contact with an outer circumferential surface of the intermediate transfer member. The toner image carried on the image carrier is primarily transferred onto the intermediate transfer member in a state where the voltage application member applies the voltage to the image carrier. The intermediate transfer member has a volume resistivity from 5×107 ?·cm to 2×1011 ?·cm inclusive. A relation ?s1/?s2?1.5 is satisfied, where ?s1 denotes a surface resistivity which is measured from the outer circumferential surface of the intermediate transfer member and ?s2 denotes a surface resistivity which is measured from an inner circumferential surface of the intermediate transfer member.
