发明名称 画像形成装置
摘要 An image forming apparatus includes a plurality of image bearing members and a control unit. After an image forming mode starts until a toner image is primarily transferred onto an intermediate transfer member from an uppermost-stream image bearing member of the plurality of image bearing members provided at an uppermost stream position, the control unit is configured to provide a toner patch onto at least one of primary transfer portions. The toner patch is formed by developing an electrostatic latent image formed on at least one of the plurality of the image bearing members, and in the image forming mode a timing at which a trailing edge of the toner patch that passes through one of the plurality of the primary transfer portions reaches a secondary transfer portion is earlier than a timing at which the recording material reaches the secondary transfer portion.
