A charging apparatus has a discharging member with a plurality of protrusions and an auxiliary member for assisting discharges by the discharging member, and an insulating member formed among the plurality of protrusions of the discharging member, so that discharge is made between the discharging member and the auxiliary member upon application of a voltage between the discharging member and the auxiliary member. Where an interval among distal ends of the plurality of protrusions of the discharging member is denoted as P and an interval between the discharging member and the auxiliary member is denoted as D, P is at least equal to or greater than D.

An image reader includes a first image-reader unit, mounted on a body of the image reader, for reading image information of an original document on a first image-reader section, a closing unit which is openably supported on the body of the image reader through a closing device, a second image-reader unit, mounted on the closing unit, for reading image information of an original on a second image-reader section, and a closed-state detector for detecting a closed state of the closing unit. The closed-state detector includes a photoemitter, a photodetector, and a light-blocking unit which blocks a light beam traveling from the photoemitter to the photodetector, by moving in operative association with the opening and closing operation of the closing unit.

A sheet conveying apparatus including a conveying path changing device, the conveying path changing device having a main conveying path for conveying a sheet, a plurality of branched paths branched from the main conveying path, a plurality of oscillatable flappers for selecting between a changed position where the sheet is guided from the main conveying path to one of the branched paths and a retracted position permitting passage of the sheet, a single solenoid for oscillating the plurality of flappers, a single link for connecting the solenoid and the flappers, and a sensor confirming movements of the flapper by detecting a movement of the link.
摘要:
A sheet interval, serving as the distance between conveyed recording materials, is properly controlled based on a kind of a recording material and any one of a printing ratio, an adhesion amount of toner, and the presence or absence of graphic data, thus allowing printing at throughput suitable for, for example, the kind of the recording material and the printing ratio without changing an image forming condition such that image quality does not vary.

The present invention relates to a sheet processing apparatus comprising an intermediate staking portion for aligning a sheet sent, a reference wall for positioning the sheet, a stapler form performing a binding operation with respect to a sheet bundle aligned by the reference wall, delivery means for delivering the sheet bundle from the intermediate stacking portion, a sheet stacking portion for stacking the sheet bundle and guide means provided above the sheet stacking portion and at an end portion on the stapler side of the end portions in the width direction of the sheet. The guide means supports an end portion on the stapler side of the sheet bundle when the sheet bundle is delivered from the delivery means in a staple mode in which the binding operation is preformed with respect to the sheet bundled.

An image forming apparatus having a sorter, includes a plurality of bins for accommodating sheet materials, the bin each having sheet material sheet inlet portion, a discharging device movable along the inlet portions of the bins to discharge the sheet material to selected one of the bins, a sheet material accommodating tray other than the bins to accommodate the sheet materials, a guiding device switchable to direct the sheet material selectively to the bin or to the sheet material accommodating tray, and a device for switching the guiding device to direct the sheet material to the discharging device when the discharging device is at a position for discharging the sheet material to the bin, and the sheet material to the accommodating device when the discharging device is not at the position.
摘要:
An image forming apparatus usable with a process cartridge detachably mountable thereto. The process cartridge includes a main cartridge containing a photosensitive member and process means as a unit. A subordinate process cartridge is detachably mountable to the main cartridge. The subordinate cartridge includes at least a developing device which is different from the developing device contained in the main cartridge so that a multi-color image can be formed if desired. The photosensitive member is used both for the main process cartridge and the subordinate cartridge.
