Abstract:
1. An image forming apparatus comprising: an image bearing member for carrying a toner image; an endless intermediary transfer belt which is movable along an endless path; a transfer member for transferring the toner image from said image bearing member onto a surface of said belt; a supporting member for supporting said transfer member; and an urging member for urging said supporting member toward said belt, wherein said transfer member includes an elastic member having a contact surface which is capable of surface contact to an inside surface of said belt without rotation relative to said supporting member, wherein said supporting member is rotatable during movement of said belt, about an axis of a rotational shaft so as to move in a direction perpendicular to a moving direction of said belt, wherein said urging member urges said supporting member to effect the surface contact of said elastic member to said belt during movement of said belt, wherein said rotational shaft is disposed at a position which is away from an inner surface of said belt in the endless path and which is upstream of said elastic member with respect to the moving direction of said belt, and wherein a position where said urging member contacts said supporting member is downstream of said rotational shaft with respect to a movement direction of said belt.
