Abstract
A sheet conveyor includes a first roller and a second roller pressurized to the first roller to hold and convey a sheet, wherein when the sheet is held between the first roller and the second roller, the first roller and second roller are separated at a space equivalent to a thickness of the sheet. The sheet conveyor has a pressurizing delay mechanism configured to bring controllably the first roller and the second roller into contact with each other after the sheet is conveyed from the first roller and the second roller.
Claims20
A sheet conveyor comprising:
- a first roller;
- a second roller pressurized to the first roller to hold and convey a sheet, wherein the first roller and the second roller are separated at a space equivalent to a thickness of the sheet when the sheet is held between the first roller and the second roller;
- and
- a pressurizing delay mechanism configured to bring controllably the first roller and the second roller into contact with each other after the sheet is conveyed from the first roller and the second roller.
An image forming apparatus comprising:
- a transfer unit configured to transfer a toner image onto a sheet;
- and
- a sheet conveyor configured to send the sheet toward the transfer unit at predetermined timing,
- wherein the sheet conveyor includes:
- a first roller;
- a second roller pressurized to the first roller to hold and convey the sheet, wherein the first roller and the second roller are separated at a space equivalent to a thickness of the sheet when the sheet is held between the first roller and the second roller;
- and
- a pressurizing delay mechanism configured to bring controllably the first roller and second roller into contact with each other after the sheet is conveyed from the first roller and second roller.
A sheet conveying method comprising:
- separating, when a sheet is held between a first roller and a second roller pressurized to the first roller to hold and convey the sheet, the first roller and the second roller at a space equivalent to a thickness of the sheet;
- and
- bringing controllably the first roller and second roller into contact with each other after the sheet is conveyed from the first roller and second roller.
