IMAGE FORMING APPARATUS

摘要

An image forming apparatus includes an image bearing member, a transfer section, a transfer bias applying section, a conveyance section, an element, a current measurement section, and a control section. The transfer section forms, in conjunction with the image bearing member, a pressing part where a recording medium is pressed. The transfer bias applying section supplies transfer current to the transfer section to apply a transfer bias to the transfer section. The element conducts when a voltage equal to or greater than a prescribed value is applied thereto. The current measurement section measures a value of leak current. The leak current is a current flowing through the element. The control section controls a value of the transfer current. The control section changes the absolute value of the transfer current based on the absolute value of the leak current.

主权项

1. An image forming apparatus comprising:
an image bearing member that bears a toner image thereon; a transfer section that forms, in conjunction with the image bearing member, a pressing part where a recording medium is pressed and that is configured to transfer the toner image from the image bearing member to the recording medium as the recording medium passes through the pressing part; a transfer bias applying section that supplies transfer current to the transfer section to apply a transfer bias to the transfer section; a conveyance section that conveys the recording medium in a conveyance direction toward the pressing part; an element that is connected with the conveyance section and conducts when a voltage equal to or greater than a prescribed value is applied thereto; a current measurement section that measures a value of leak current, the leak current being a current flowing through the element; and a control section that controls a value of the transfer current, wherein the control section changes an absolute value of the transfer current based on an absolute value of the leak current.
