Abstract
An image forming apparatus includes a sheet stacking portion, a feed portion, a transfer portion transferring a toner image on a sheet fed by the feed portion, and a switching portion. The switching portion switches the sheet stacking portion between a grounded condition in which the sheet stacking portion is electrically earthed and an insulated condition in which the sheet stacking portion is electrically insulated. The sheet stacking portion is switched into the insulated condition in a state in which the transfer bias is applied and the sheet stacking portion is switched into the grounded condition in a state in which no transfer bias is applied.
