Abstract
An apparatus includes a developer and a moveable support that is moveable in response to actuation by an image forming device. The apparatus further includes a toner transfer modulator on the moveable support, the toner transfer modulator moveable with the moveable support between different positions to differently affect transfer of a toner to a photoreceptor or a transfer member, where the moveable support is to move the toner transfer modulator to a first position to disrupt the transfer of the toner to the photoreceptor or the transfer member during an image forming operation of the image forming device.
Claims15
A cartridge for an image forming device, the cartridge comprising:
- a developing device including a developing roller and a moveable support to be moved by an actuator of the image forming device;
- a photoreceptor on which an electrostatic latent image is formed;
- a toner transfer modulator linked to the moveable support and moveable between a first position to disrupt the transfer of the toner to the photoreceptor during an image forming operation of the image forming device and a second position to allow transfer of the toner to the photoreceptor or the transfer member by the actuator of the image forming device.
A cartridge for an image forming device, the cartridge comprising:
- a developing device including a developing roller and a moveable support to be moved by an actuator moveable between different positions by a drive assembly of the image forming device during an image forming operation of the image forming device;
- a photoreceptor on which an electrostatic latent image is formed;
- and
- a toner transfer modulator linked to the moveable support and moveable, in response to a movement of the actuator, in the image forming device between a first position and a second position to control a transfer of a toner to a photoconductive drum or a transfer member,
- wherein the toner transfer modulator when in the first position disrupts the transfer of the toner to the photoconductive drum or the transfer member during the image forming operation of the image forming device, and
- wherein the toner transfer modulator when in the second position allows for a normal transfer of the toner to the photoconductive drum or the transfer member during the image forming operation of the image forming device.
A method comprising:
- during an image forming operation of an image forming device to form an image on a target medium:
- operating a photoreceptor;
- and
- activating a mechanism that moves a moveable support by an actuator of a cartridge from a first position to a second position, wherein the first position sets a toner transfer modulator linked to the moveable support and in a first physical position and causes the toner transfer modulator in the first physical position to disrupt a transfer of a toner to the photoreceptor or a transfer member, and wherein the second actuator position sets the toner transfer modulator in a different second physical position and causes the toner transfer modulator in the second physical position to allow a normal transfer of the toner to the photoreceptor or the transfer member.
