Abstract

An image-forming apparatus includes an image-bearing member supporting a toner image, a transfer portion at which the toner image on the image-bearing member is transferred on a sheet; and first and second guides that guide the sheet to the transfer portion and respectively have first and second contact portions so that a surface of the sheet on which the toner image is transferred contacts these portions. The first contact portion is located at an upstream side of the second contact portion in a sheet-conveying direction. After a rear end of the sheet passes the first contact portion, the rear end of sheet passes the second contact portion while bending the second guide toward the image-bearing member. The second guide is bent from a position of an upstream side in the sheet-conveying direction with respect to a position of the first contact portion which the rear end of the sheet finally contacts when the rear end of the sheet passes the first contact portion.

Dependent claims

An image-forming apparatus comprising:

an image-bearing member supporting a toner image;
a transfer portion at which the toner image on the image-bearing member is transferred on a sheet;
a first guide configured to guide the sheet to the transfer portion, the first guide having a first contact portion, a surface of the sheet on which the toner image is transferred contacting the first contact portion;
and
a flexible second guide configured to guide the sheet to the transfer portion, the second guide having a second contact portion, the surface of the sheet on which the toner image is transferred contacting the second contact portion,
wherein the first contact portion is located on an upstream side of the second contact portion in a sheet-conveying direction,
wherein after a rear end of the sheet passes the first contact portion, the rear end of the sheet passes the second contact portion while the sheet causes the second guide to bend toward the image-bearing member, and
wherein the second guide is bent from a position of an upstream side in the sheet-conveying direction with respect to a position of the first contact portion which the rear end of the sheet finally contacts when the rear end of the sheet passes the first contact portion.
