Abstract
An image forming apparatus, including an image carrier, a toner image forming section which forms a toner image on the image carrier, a transfer section which transfers the toner image formed on the image carrier to an intermediate transfer member or a recording sheet, a cleaning section which includes a brush and a blade to remove toner particles remaining on the image carrier after the toner image are transferred by the transfer section, and a control section executes a blade cleaning mode in which toner particles having an opposite polarity against the toner particles adhered onto the blade are sent to the cleaning section while an amount of toner particles to be removed by the brush is changed.
Claims19
An image forming apparatus, comprising:
- an image carrier;
- a toner image forming section which forms a toner image on the image carrier;
- a transfer section having a transfer output, wherein the transfer section transfers the toner image formed on the image carrier to an intermediate transfer member or a recording sheet;
- a cleaning section which includes a blade to remove toner particles remaining on the image carrier after the toner image is transferred by the transfer section, wherein toner particles having a first polarity are adhered on the blade after the toner image is transferred by the transfer section;
- and
- a control section which executes a blade cleaning mode after the toner image is transferred by the transfer section, wherein the control section controls the transfer output to allow toner particles having a second polarity to remain on the image carrier to be delivered to the blade, wherein the controlled transfer output is stopped as changing a setting of the transfer output, wherein the first polarity and second polarity are opposite in electric charge.
An image forming apparatus, comprising:
- an image carrier;
- a toner image forming section which forms a toner image on the image carrier;
- a transfer section having a transfer output, wherein the transfer section transfers the toner image formed on the image carrier to an intermediate transfer member or a recording sheet;
- a cleaning section which includes a blade to remove toner particles remaining on the image carrier after the toner image is transferred by the transfer section, wherein toner particles having a first polarity are adhered on the blade after the toner image is transferred by the transfer section;
- a control section which executes a blade cleaning mode after the toner image is transferred by the transfer section, wherein the control section controls the transfer output to allow toner particles having a second polarity to remain on the image carrier to be delivered to the blade, wherein the first polarity and the second polarity are opposite in electric charge;
- and
- a torque detecting section which detects a loading torque of a driving section which rotates the image carrier, wherein the control section determines whether the blade cleaning mode is to be selected or not based on an information detected by the torque detecting section.
