IMAGE FORMING APPARATUS

摘要

One aspect of the present invention provides an image forming apparatus that can prevent degradation of sheet feeding performance at low cost. A drive transmission portion 200B is provided between a driving motor 227 that drives a conveying roller 250 provided in an apparatus body and a body-side lifting portion 200C that drives a lifter mechanism 200A of a sheet feeding cassette 201 mounted on the apparatus body. When the sheet feeding cassette 201 is mounted on the apparatus body, the drive transmission portion 200B selectively transmits drive of the driving motor 227 to the lifter mechanism 200A through the body-side lifting portion 200C to lift a stacking plate 206 by a predetermined amount.

主权项

1. An image forming apparatus comprising:
an image forming portion that forms an image on a sheet; a sheet storage portion that is drawably mounted on an apparatus body, the sheet storage portion including a sheet stacking portion that stacks a sheet and is able to lifted and a lifting portion that lifts the sheet stacking portion; a sheet feeding portion that feeds a sheet while abutting the sheet on a sheet stacked on the lifted sheet stacking portion; a driving portion that drives a driven portion; a body-side lifting portion that is provided in the apparatus body to engage with the lifting portion of the sheet storage portion mounted on the apparatus body; a drive transmission portion that is provided between the driving portion and the body-side lifting portion, the drive transmission portion selectively transmitting drive of the driving portion to the lifting portion of the sheet storage portion through the body-side lifting portion to lift the sheet stacking portion, the drive of the driving portion being transmitted to the driven portion; and a controller that controls the drive transmission portion.
