Abstract
An image forming apparatus includes a rotatable image bearing member, a developing device including a developing container and a developer carrying member, a rotatable intermediary transfer member, and a carrier collecting device including a rotatable sleeve and a magnet. With respect to a rotational direction of the intermediary transfer member, the collecting device is disposed downstream of a first transfer position where a toner image borne on the image bearing member is transferred onto the intermediary transfer member and upstream of a second transfer position where the toner image borne on the intermediary transfer member is transferred onto a recording material.
Claims8
An image forming apparatus comprising:
- a rotatable image bearing member on which an electrostatic latent image is formed;
- a developing device including a developing container configured to accommodate a developer containing non-magnetic toner and a magnetic carrier, and a developer carrying member configured to carry the developer for developing the electrostatic latent image, formed on the image bearing member, into a toner image;
- a rotatable intermediary transfer member onto which the toner image borne on the image bearing member is transferred;
- a carrier collecting device including a rotatable sleeve provided opposed to the intermediary transfer member and a magnet non-rotationally provided inside the sleeve and configured to collect the carrier on the intermediary transfer member, and
- a voltage applying portion configured to apply a voltage of the same polarity as a charge polarity of the non-magnetic toner to the sleeve,
- wherein with respect to a rotational direction of the intermediary transfer member, the collecting device is disposed downstream of a first transfer position where the toner image borne on the image bearing member is transferred onto the intermediary transfer member and upstream of a second transfer position where the toner image borne on the intermediary transfer member is transferred onto a recording material.
