The quantity of light of an optical sensor including a light emission portion and a light reception portion is adjusted through calculation before sheet detection is performed. In order to perform the light quantity adjustment, a voltage to be applied to the light emission portion of the optical sensor is obtained by performing calculation based on a relation between a voltage applied to the light emission portion before the adjustment and an output from the light reception portion before the adjustment. Then, it is judged whether the obtained voltage exists within a predetermined range and, if a positive result is obtained, the light quantity adjustment is ended. Further, a signal requesting the cleaning of the optical sensor is outputted in accordance with a value of the obtained voltage.

A recording intermediate belt 15 which is made endless so as to travels around a continuous path has image formation areas and non-image formation areas alternately provided on an outer surface thereof. Images of different colors are sequentially formed in the image formation areas by recording heads 21b through 23b respectively provided in first through third image formation sections 21 through 23. The recording heads 21b through 23b of the first through third image formation sections 21 through 23 are separated from each other by a distance which is greater than a length of an image formation area in a traveling direction of the recording intermediate belt 15. The recording heads 21b through 23b are each pressed onto the recording intermediate belt 15 in a non-image formation area immediately preceding an image formation area and starts an image formation operation. The image formation operation is stopped when the recording heads 21b through 23b each face a non-image formation area immediately subsequent to the image formation area. Thus, a clear full-color image can be formed with the image formed in each image formation section being free from color non-uniformity.

An image processing apparatus is provided which comprises an image reading section for reading an original document by causing an image reading head of the image reading section to move relative to an original document; an image recording section for recording an image on a recording medium in accordance with an image signal; a power source for supplying power to the image reading section and the image recording section; and a control device for controlling the speed of movement of the image reading head according to an operating state of the image recording section. The image processing apparatus of the invention overcomes problems associated with the use of prior art image forming apparatus, such as multi-function copying machines, that include an image reading section and an image recording section, and which require the use of large-capacity power sources for supporting the electrical loads of various components that may be operating simultaneously within the individual apparatuses.

This invention relates to an electron tube having a structure for enabling a stable operation for a long time. In the electron tube, at least a confining mechanism is arranged between a photocathode and the electron incident surface of a semiconductor device, which are arranged to oppose each other. In the arrangement, the area of the opening of the confining mechanism is at least equal to or smaller than that of the electron incident surface, thereby confining the orbits of photoelectrons from the photocathode. This structure avoids bombardment of electrons arriving at portions other than the electron incident surface of the semiconductor device and prevents the semiconductor device from being unnecessarily charged.

The present invention relates to an electron tube includes, at least, a cathode electrode and a face plate having a photocathode which are arranged at one end of a body, and a stem arranged at the other end of the body for defining the position of an electron entrance surface where the electron emitted from the photocathode reaches. The object of the present invention is to provide an electron tube which can reduce its size and has a structure for improving the workability in its assembling process. In particular, the electron tube in accordance with the present invention comprises a bonding ring, provided between the face plate and the cathode electrode, for bonding the face plate and the cathode electrode together. The bonding ring is made of a metal material selected from the group consisting of In, Au, Pb, alloys containing In, and alloys containing Pb.

An electrified portion electric-potential, exposed portion electric-potential, and developing biasing electric-potential are controlled so as to obtain a constant ratio between an input level in exposure to generate the electrostatic latent image and the density associated with the toner-made image resulting from the developing for said electrostatic latent image. A target electric-potential determination table obtains therefrom respective target values for the electrified portion electric-potential, exposed portion electric-potential, and developing biasing electric-potential, wherein the target values obtained may vary depending on variation in the relevant characteristics due to ambience and/or aging of the developing system. A control-input determination unit determines control-input for controlling the electrified portion electric-potential, exposed portion electric-potential and developing biasing electric-potential so that these potentials equal their respective target values.
