Abstract
An image forming apparatus includes an image bearer to bear a visible image, a transfer device to transfer the visible image from the image bearer onto a recording medium, a separator to separate the recording medium from the image bearer, a separation bias application device to apply a separation bias to the separator; and a controller to control the separation bias. When the recording medium fed in the image forming apparatus is either a black sheet or a metallic sheet, the controller sets the separation bias smaller than a predetermined separation bias value for a reference sheet type other than the black sheet and the metallic sheet.
Claims8
An image forming apparatus, comprising
- an image bearer to bear a visible image;
- a transfer device to transfer the visible image from the image bearer onto a sheet;
- a separator to separate the sheet from the image bearer;
- a separation bias application device to apply a separation bias to the separator;
- and
- a controller to control the separation bias;
- and
- a selection input device to input, to the controller, a selected sheet type selected by a user,
- wherein, when either a black sheet or a metallic sheet is selected as the selected sheet type by the selection input device, the controller sets the separation bias smaller than a predetermined separation bias value for a reference sheet type other than the black sheet and the metallic sheet, regardless of whether the sheet includes carbon and regardless of whether the sheet includes a metal layer.
A method of separating a sheet from an image bearer in an image forming apparatus, the method comprising:
- applying a separation bias to the sheet;
- receiving, from an input selection device, input of a selected sheet type of the sheet selected by a user;
- and
- reducing the separation bias from a predetermined separation bias value for a reference sheet type other than a black sheet and a metallic sheet when either the black sheet or the metallic sheet is selected as the selected sheet type by the selection input device, regardless of whether the sheet includes carbon and regardless of whether the sheet includes a metal layer.
