Provided is an image processing apparatus that detects a maintenance event required for the maintenance thereof and displays video data on a screen by reproducing the video data which indicates a maintenance procedure for resolving the detected maintenance event. Then, the image processing apparatus displays a specific scene included in the video data on the screen after completion of reproduction of the video data.

Image processing apparatus, control method, and storage medium in which the load can be suppressed during a maintenance event

An image processing apparatus capable of facilitating synchronization of a maintenance moving image between an image processing apparatus and a mobile information terminal, thereby making it possible to more efficiently show the moving image to a user who performs a maintenance operation. The mobile information terminal is registered as a distribution destination of the moving image. The moving image for current reproduction and display on the apparatus and information of the reproduction position of the moving image are distributed to the terminal to thereby cause the terminal to reproduce and display the moving image from the position. The position is changed based on information of a change in the reproduction position received from the terminal. When the position is changed on the image apparatus, information of a change in the position is transmitted to the terminal, to thereby cause the terminal to change the position.

Image processing apparatus that performs reproduction synchronization of moving image between the same and mobile information terminal, method of controlling image processing apparatus, storage medium, and image processing system

A charging method of an electrostatic image developer which makes it possible to electrically charge an insulating one-component developer or a two-component developer consisting of a toner and a carrier to a desired charged state and which comprises introducing the developer into a charging space between a pair of sheet-like charging members opposing each other in which space an alternating field is formed, and oscillating the developer by means of the alternating field for charging it. A developing method of a non-contact or contact system which develops the electrostatic image by use of the developer charged electrically by the above-mentioned charging method.

Method of developing electrostatic images using two component developer

A developing device for use in an electrophotographic copying machine or electrostatic recording apparatus includes a stirring blade for mixing the developer. The driven shaft driving the stirring blade is intermittently revolved in a reverse direction to the main driving shaft directly connected to the developing sleeve by a mechanism incorporated between the main shaft and the driven shaft.

Developing device

In the developing apparatus for producing an electrostatic latent image on a charge retaining member such as a drum, a rotating member for producing a shifting magnetic field is used to transport magnetic toner from a toner source to a developing area on the drum. The amount of toner so transported is regulated by the present invention by a magnetizable member positioned adjacent the rotating member in front of the developing area, the magnetizable member being characterized by a curved surface on which a shifting magnetic field is induced by the said rotating member and which attracts excess toner from the latter.

Developing apparatus

Method of charging electrostatic developer

A recording apparatus includes a toner retaining member such as a photosensitive drum, a toner collector, a cleaning device for cleaning toner off of the toner retaining member, and a toner guide member for guiding toner away from the toner retaining member. The guide member has a plurality of spaced apart front contact end portions in contact with the toner retaining member for guiding toner which is cleaned from the toner retaining member to the toner collector, at least the front contact end portions of the toner guide member which are in contact with the toner retaining member being in a comb-teeth shape. Preferably, at least the front contact end portions of the toner guide member are fibers.

Cleaning apparatus for recording apparatus

An apparatus for detecting the density (concentration) of toner in a developer for an electrostatic recording apparatus includes an operatively moveable surface for carrying developer onto an electrostatic latent image bearing member during image development, a scraper element having at least a flat surface for scraping developer from the movable surface in a substantially steady and uniform stream along the flat face, and a substantially flat detection coil assembly having oppositely-directed faces. The coil assembly is mounted on, spaced apart from, and substantially parallel to the flat face of the scraper so that the stream of developer passes along both coil assembly faces directly after being scraped from the moveable surface, thereby enhancing the toner density detection sensitivity of the coil assembly.

Apparatus for detecting toner density

A copying apparatus having a power transmission means in which arranged between the plurality of driven means and the driving system is a power transmission control mechanism. Said power transmission control system is capable of reducing and absorbing the vibrations generated through the driving system and stably supplying the power to the plurality of driven means. Said power transmission control mechanism comprises a flange connected to said plurality of driven means, a flange connected to said driving system and an elastic member inserted beween said two flanges.

Power transmission control mechanism for use in the copying apparatus

A temperature sensing device for a heated roll, which includes an insulated support member and a thermocouple of bimetallic foil extending around the support member for sensing the surface temperature of the heated roll, and a resilient member interposed between the thermocouple and the insulated support member for pressing the thermocouple in abutment against the surface of the heated roll so as to increase the contact area therebetween.

Temperature sensor for use in a heated roll

Apparatus for cleaning residual toner from an electrostatic recording medium is provided wherein a brush is located adjacent the medium and a toner seizer is located adjacent the brush to remove toner carried by the brush.
