摘要:
In a apparatus for detecting toner shortage in a developing unit for use in an image recording system which forms a latent electrostatic image on a carrier by exposure based on an image signal and which develops the latent image to record the image, provided are a toner shortage sensor in a container for checking as to the presence or absence of a toner in the container at the location of the toner shortage sensor, a counter section for counting in a cumulative manner the number of image prints and the number of pixels produced by the image recording system when the toner shortage sensor detects a toner shortage, the counter section for successively subtracting the number of image prints and the number of pixels from the associated cumulative totals when the sensor detects the presence of toner in the container, and a control section for stopping at least the operation of the image recording system when the sumulative counting value of either the number of image prints or the number of pixels has reached a predetermined value.

A method for forming a food product into a circular shape, wherein both ends of an elongated food product are connected each other and closed, or into a C-shape, wherein both ends of the elongated food product face each other and opened. The method includes (a) fixing one end of the elongated food product to a rotatable core member, (b) pressing the food product toward the core member by moving the core member close to and away from a pressing roller, when the food product is formed into a circular shape by being wound around the core member by rotating the core member, and (c) separating the formed food product and the core member by releasing the food product from the core member, after forming the food product 3 into a required shape by being wound around the core member.

Storage means 15 for storing information regarding the measuring electrode 10 in the measuring electrode 10, or in a cable 12 or a connector 13 for connecting the measuring electrode 10 to the instrument body 20.
摘要:
A developing apparatus using monocomponent developer comprising: monocomponent magnetic toner; a developer carrying body for carrying and transporting the monocomponent magnetic toner; a magnetic field generation unit fixed inside the developer carrying body; a developer supply unit for supplying the developer carrying body with the monocomponent magnetic toner; and a developer trimming member furnished to the developer supply unit for pressed contact with the circumference of the developer carrying body. The developer trimming member is made of a spring material and tipped with a sliding part which contacts the circumference of the developer carrying body slidingly and which is made of a rubber material. In this setup, the following condition is met:aP>bPwhere, P stands for the initial point of contact of the sliding part with the developer carrying body, a for the upstream end position of the sliding part in the direction of sliding, b for the downstream end position of the sliding part in the direction of sliding, aP for the length of the line segment connecting the position a with the point P, and bP for the length of the line segment connecting the position b with the point P.
