发明名称 IMAGE FORMING APPARATUS
摘要 An image forming apparatus includes a plurality of image bearing members; a rotatable intermediary transfer member for carrying toner images transferred from the plurality of image bearing members in contact with the plurality of image bearing members; a transfer member for press-contacting to the intermediary transfer member to form a transfer portion, at which the toner images on the intermediary transfer member are to be transferred onto a recording material; and a control portion for controlling an image forming operation so that, during execution of a continuous image forming mode in which images are formed on a plurality of recording materials conveyed with a preset minimum interval, a recording material passes through the transfer portion and thereafter transfer of a toner image to be formed on a subsequent recording material from an image bearing member, located upstream of the transfer portion and most downstream of the plurality of image bearing members with respect to a rotational direction of the intermediary transfer member, onto the intermediary transfer member is started.
