A molding system to manufacture a three-dimensional object corresponding to a three-dimensional model. The molding apparatus includes a slice data generation unit to generate slice data from three-dimensional shape data of the three-dimensional model, and a lamination unit to laminate a layer of a molding material on the basis of the slice data. The slice data generation unit analyzes data, and, if a region in which a layer of a second molding material different from a first molding material is to be laminated on a layer of the first molding material and in which it is difficult to laminate the layers is extracted, modifies the data of a region of at least one of an ith layer and an (i+1)th layer to data in which a portion in which the first molding material is disposed and a portion in which the second molding material is disposed.

A shaping apparatus includes a storage section that stores in advance a first relationship between a temperature of a shaping material and a heating time at a time at which oxidation of the shaping material starts as the shaping material is heated; and a control section that estimates a timing at which the oxidation of a material layer starts, based on an acquisition result from a temperature acquisition section, a measurement result from a time measurement section, and the first relationship stored in the storage section when the material layer on a conveyance body is preheated by a preheating section, and reduces a front surface temperature of the material layer on the conveyance body before the oxidation of the material layer starts.

An image forming apparatus sequentially transfers toner images formed on a plurality of photosensitive drums onto an intermediate transfer member or a transfer material to form an image. The image forming apparatus includes an intermediate transfer belt provided with electrical conductivity, and a power supply for applying a voltage to a secondary transfer roller to pass a current from the secondary transfer roller to the plurality of photosensitive drums via the intermediate transfer belt, thus primarily transferring the toner images from the plurality of photosensitive drums onto the intermediate transfer belt.

Image forming apparatus having a power supply common to primary transfer and secondary transfer

To provide a cleaning blade having an elastic body portion containing urethane rubber and a support member supporting the elastic body portion. A free end portion of the elastic body has a first region in which the Young's modulus gradually decreases in the depth direction from the principal surface facing the surface of the member to be cleaned on the edge face side and a second region in which the Young's modulus does not vary in the depth direction from the principal surface on the side closer to the support member relative to the first region.

The present invention relates to an image forming apparatus that forms an image by consecutively superposing toner images that have been formed on a plurality of photosensitive drums, on an intermediate transfer member or a transfer medium. The image forming apparatus is made compact and operates at a low cost. Since a current supply member supplies a current in a rotational direction of an intermediate transfer belt, multiple first transfer portions do not need corresponding voltage sources. Even in the case where a charging member supplies a current, the potential of the intermediate transfer belt is maintained at a predetermined potential by a constant-voltage element connected to support rollers.

A fluorine-containing resin-coated pressure roller exhibiting excellent anti-toner soiling characteristic even at low roller temperatures is provided. The pressure roller includes a cylindrical metal substrate, and a rubber elastic layer, an adhesive layer and a fluorine-containing resin release layer disposed in this order on and successively coating the cylindrical metal substrate. The pressure roller has a surface exhibiting a micro-rubber hardness of at most 50 deg., a contact angle with water of at least 105 deg. and a ten point-average surface roughness Rz of at most 3.0 &mgr;m. The pressure roller may be suitably combined with a fixing film to provide a film heating-type fixing device suitably used in an electrophotographic image forming apparatus.
