Abstract:
An anisotropic conductive sheet interposed between a circuit board such as a substrate and various circuit parts to render them conductive and its manufacturing method. The anisotropic conductive sheet has a fine pitch required by the recent highly integrated circuit boards and electronic parts. In the anisotropic conductive sheet in which conductive members are scattered in a nonconductive matrix, the conductive members (e.g., 24) penetrate through the sheet (10) in the direction of thickness and conductive auxiliary layers (e.g., 25) are in contact with the conductive members (e.g., 24).
Abstract:
The invention provides a film driving apparatus in which no adverse effect is caused by a change in the circumferential length of a film even if there arises the change in circumferential length of the film due to environmental fluctuation. In the film driving apparatus, an endless film 1 supported by a driving roller 2, a film support roller 4 and a skew correction roller 3 is rotated in a predetermined direction by the rotation of a driving roller 2. The skew correction roller 3 has a structure in which one end thereof is movable with the other end as a fulcrum. The movement trajectory of the movable end portion of the skew correction roller 3 is an elliptic trajectory not causing any change in the circumferential length of the film 1.

An image forming apparatus that forms an image using a photoconductor body includes a switching unit which effects switching between a state in which a cleaner is operated for the photoconductor body, and a state in which the cleaner is not operated for the photoconductor body. A control unit is provided which controls a setting change of an image formation condition between a case where the cleaner is operated by the switching unit, and a case where the cleaner is not operated by the switching unit. The switching unit includes a detection unit which detects the kind of paper on which an image is formed, and the switching unit switches on/off the cleaner in accordance with a detection result of the detection unit.

Abstract:
There is provided a technique in which when an image forming processing with toners of plural colors is performed, a residual toner on a transfer-receiving member to which toner images are transferred by plural image forming units is not discarded, but is reused as a black toner, and a deterioration in picture quality due to a change in color tone of the black toner is prevented. An image forming apparatus is for performing an image forming processing by plural image forming units to form toner images of colors different from each other on a transfer-receiving member moved in a specified direction, and includes a toner collecting unit to collect toners remaining on the transfer-receiving member, a ratio judgment unit to judge a mixing ratio of toners of plural colors included in the toners collected by the toner collecting unit, and a toner replenishing unit to replenish an insufficient color toner to the toners collected by the toner collecting unit based on the mixing ratio judged by the ratio judgment unit so that the mixing ratio becomes a specified ratio.
