Abstract
A sheet conveying apparatus includes: a shutter member against which a leading edge of a sheet being conveyed abuts, for a skew feed correction, wherein the shutter member is pressed and moved by the sheet; and an actuation member which moves the shutter member that has been pressed and moved by the sheet being conveyed to a retracted position at which the shutter member is retracted from a sheet conveying path and holds the shutter member at the retracted position until the leading edge of the sheet being conveyed by the second conveying rotary member is nipped by the transfer nip portion.
Claims12
A sheet conveying apparatus, comprising:
- a first conveying rotary member which conveys a sheet;
- a second conveying rotary member and a third conveying rotary member which are sequentially disposed downstream of the first conveying rotary member in a sheet conveying direction;
- a shutter member against which a leading edge of the sheet being conveyed abuts downstream of the first conveying rotary member and upstream of a nip portion of the second conveying rotary member, wherein the shutter member is pressed and moved by the sheet being conveyed;
- and
- an actuation member which moves the shutter member that has been pressed and moved by the sheet being conveyed to a retracted position at which the shutter member is retracted from a sheet conveying path and holds the shutter member at the retracted position until the leading edge of the sheet being conveyed by the second conveying rotary member is nipped by the third conveying rotary member.
An image forming apparatus, comprising:
- a first conveying rotary member which conveys a sheet;
- a second conveying rotary member disposed downstream of the first conveying rotary member in a sheet conveying direction;
- an image transfer portion which transfers a toner image to a sheet at a transfer nip portion disposed downstream of the second conveying rotary member in the sheet conveying direction;
- a fixing portion which fixes, to the sheet, the toner image transferred to the sheet by the image transfer portion;
- a shutter member against which a leading edge of the sheet being conveyed abuts downstream of the first conveying rotary member and upstream of a nip portion of the second conveying rotary member, wherein the shutter member is pressed and moved by the sheet being conveyed;
- and
- an actuation member which moves the shutter member that has been pressed and moved by the sheet being conveyed to a retracted position at which the shutter member is retracted from a sheet conveying path and holds the shutter member at the retracted position until the leading edge of the sheet being conveyed by the second conveying rotary member is nipped by the transfer nip portion.
