The image forming apparatus includes a photoreceptor, a charger that charges a surface of the photoreceptor, an exposer that irradiates the charged surface of the photoreceptor with light to form an electrostatic latent image, a developer that develops the electrostatic latent image to form a toner image, a transferer that transfers the toner image onto a recording medium, a cleaner that removes residual toner on the surface of the photoreceptor, and an inductor. The photoreceptor includes a conductive substrate and a photoreceptive layer provided on the conductive substrate. The conductive substrate is connected to a ground via the inductor.

An image forming apparatus is provided with a high-voltage substrate, a motor and a DC power source. The high-voltage substrate has a developing positive bias circuit and a developing reverse bias circuit which are connected to each other in parallel, in which the developing positive bias voltage is combined with developing reverse bias voltage to generate developing bias voltage. The high-voltage substrate includes a interruption switch for interrupting a reverse current from the motor to the developing reverse bias circuit in a case where an interlock switch is turned off at the time of emergency stop, in which, when the reverse current is interrupted by the interruption switch, electric power that is accumulated in the capacitor is supplied to the developing positive bias circuit to apply the developing positive bias voltage as the developing bias voltage to the developing roller for a given length of time.

A display device of an electronic apparatus according to the present invention is a display device of an electronic apparatus for setting a plurality of conditions for a process of the electronic apparatus through an input portionwhile displaying the conditions before the electronic apparatus performs the process in accordance with the conditions. The device comprises a determination portionof determining whether or not each of the conditions has not yet been set, and a liquid crystal display panelof displaying notifying information indicating to what degree conditions remain to be set. The liquid crystal display paneldisplays buttons for setting the respective conditions on a screen thereof, and displays button(s) which have already been pressed as being unfilled and the number of buttons which have not yet been pressed. Therefore, by viewing the screen, the number and types of conditions which have not yet set can be known.

An image forming apparatus is provided that, is capable of physically preventing taking-out of the set document, even when a thick copy-prohibited document is set on a document reading device. The image forming apparatus is configured to place a document on a document table, and at least the document is read by closing a pivotally supported document cover portion to cover the document and the image forming apparatus comprises a read-out document determining portion and when the document is determined to be a copy-prohibited document, and prevents the document from being taken out from the document table by locking the rotation of the pivotally supported portion of the document cover.

An image forming apparatus includes an image forming unit, a paper transport unit, and a control unit for supplying the image forming unit with image data for a plurality of pages so that the image forming unit forms images page by page on sheets transported by the paper transport unit, wherein, when the image data for each page includes data representative of blanks on a leading end side and on a tail end side of the page in a paper transport direction, the control unit deletes the data representative of the blank either on the leading end side or on the tail end side from the image data prior to supplying the image forming unit with the image data, and controls the paper transport unit so that a plurality of sheets are transported sequentially to the image formation unit in a multiple state in which one sheet partially overlaps with another in the paper transport direction by a length corresponding to the deleted data representative of the blank.
