An image-forming apparatus having a main body frame and a photosensitive medium on which a toner image is formed, the image-forming apparatus comprising:
- a transfer roller that transfers the toner image onto a sheet of print medium;
- and
- a device to attach/detach the transfer roller to/from the main body frame;
- wherein the device supports an end of a transfer roller axis to rotate with respect to the main body frame, and a motion of the device automatically separates/locks the end of the transfer roller axis from/to the main body frame by causing an ascending/descending of the end of the transfer roller axis in a direction.
A device to attach/detach a transfer roller to/from a main body frame of an image-forming apparatus, wherein the device supports an end of a transfer roller axis to rotate with respect to the main body frame, and a motion of the device automatically separates/locks the end of the transfer roller axis from/to the main body frame by causing an ascending/descending of the end of the transfer roller axis in a direction.
A method to attach/detach a transfer roller to/from a main body frame of an image-forming apparatus, the method comprising:
- supporting an end of a transfer roller axis with a device;
- and
- automatically separating/locking the end of the transfer roller axis from/to the main body frame with a motion of the device by causing an ascending/descending of the end of the transfer roller axis on the device in a direction.
