Abstract:
An image forming apparatus includes a rotatable mirror for scanningly deflecting a laser beam modulated in accordance with information to be recorded, a movable photosensitive member to be scanned by the modulated laser beam, an assembly for containing therein the rotatable mirror and the photosensitive member. The assembly includes a first part and a second part supported to the first part rotatably about a pivot. The rotatable mirror is located away from the exposure station toward or beyond the pivot.
Abstract:
A drum brake device produces a stable braking force at a predetermined boosting ratio in response to a brake operation force input thereto, even if the friction characteristics of the interface of the brake drum and the brake shoe varies, without increasing the size of the wheel cylinder. The drum brake device includes an input detector that detects a hydraulic braking pressure output from a master cylinder, and produces a signal representative of the detected hydraulic braking pressure as an input force to the drum brake device; an output detector that detects an anchor reaction force generated at the time of braking and produces a signal representative of the detected anchor reaction force as an output force of the drum brake device; electromagnetic valves capable of controlling the supply of a hydraulic braking pressure supplied from the master cylinder to a wheel cylinder; and a control circuit that controls the operations of the electromagnetic valves in accordance with output signals of the input detector and the output detector so that the output force is limited to a force equal to or smaller than a force defined by a predetermined boosting ratio.
Abstract:
The present invention provides a method for recycling a process cartridge removably mountable to an image forming apparatus, comprising the steps of: (a) dividing a process cartridge into a first frame including an image bearing member, and a second frame including a developing means and a developer containing means for containing developer used by the developing means and having an opening through which the developer is supplied to the developing means; (b) thereafter, removing the developing means from the second frame; (c) thereafter, replenishing developer to the developer containing means through the opening; (d) thereafter, removably attaching a seal for closing the opening to the opening; and (e) thereafter, locking the first and second frames to each other, thereby assembling the process cartridge.
Abstract:
A process cartridge detachably mountable to a main assembly of an image forming apparatus includes an electrophotographic photosensitive member; a process device actable on the photosensitive member; a toner container for containing toner for developing a latent image formed on the electrophotographic photosensitive member, the toner container having an opening for permitting supply of the toner to a developing portion therefrom; a sealing member for sealing the opening; and a seal mounting portion for permitting a sealing member a plurality of times.
Abstract:
In order to prevent the eccentricity of a rotary shaft for rotatably supporting an image bearing member used with an image forming apparatus when the image bearing member is rotated, a projection is provided on an outer peripheral surface of the rotary shaft fitted into a fitting hole formed in a casing for securing the rotary shaft.

Abstract:
This invention relates to an image forming apparatus having a convey path comprising lateral movement apparatus for controlling a widthwise position of a sheet member to be conveyed, wherein the lateral movement apparatus is curved in a convey direction.
Abstract:
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.
Abstract:
A color cathode ray tube comprises a fluorescent screen having one or more phosphors on an inner surface of a face glass for plural emission colors, and the face glass which contains a Nd.sub.2 O.sub.3 and other colorants to give a wavelength selectivity of light transmission of said face glass.

Abstract:
The disclosed cathode ray tube for a display system includes a convex face plate having a radius of curvature less than its outside maximum dimension and a phosphor screen disposed on the inner surface of the face plate and entirely irradiated with an unfocussed beam of electrons from an electron gun to luminesce in a monochromatic color. The face plate may be formed of glass having a color identical to or approximating the luminescent color of the phosphor screen. Also a phosphor for the screen may be colored to have a color identical to or approximating its luminescent color.
