Abstract
A detection unit is disposed between a feeding unit and a secondary transfer unit on a conveyance path, and detects a transfer material that is conveyed. A control unit, if the detection unit cannot detect the transfer material by a predetermined timing after a feeding operation by a feeding unit, moves the secondary transfer unit away from a intermediate transfer member, causes the intermediate transfer member to continue rotating, and causes the feeding unit to retry feeding of the transfer material.
Claims17
An image forming apparatus, comprising:
- an image carrier on which a latent image is formed;
- a developing unit which develops the latent image;
- a transfer member which carries an image developed on the image carrier;
- a transfer unit which transfers the image carried by the transfer member to a recording material at a transfer position;
- and
- a feeding unit which feeds the recording material to the transfer position,
- wherein, in a case the recording material is not fed when an operation of feeding the recording material is tried, the developing unit moves to a position different from a developing position while the transfer member is carrying the image, and the feeding unit retries feeding of the recording material.

An image forming apparatus comprising:
- an image carrier on which a latent image is formed;
- a developing member which develops the latent image formed on the image carrier;
- a transfer member to which an image developed on the image carrier is transferred;
- a transfer unit which transfers the image carried by the transfer member to a recording material;
- and
- a feeding unit which feeds the recording material to the transfer unit,
- wherein, in a case the recording material is not fed when an operation of feeding the recording material is tried, the feeding unit performs the operation of feeding again,
- the developing member is switchable between a contact state where the developing member contacts with the image carrier and a non-contact state where the developing member is not in contact with the image carrier, and
- when the feeding unit performs the operation of feeding again, the developing member switches to the non-contact state.
