A multi-band transceiver has a function of sharing transmitted and received signals of multiple frequency bands by the same antenna. The multi-band transceiver mounts multiple filters that correspond to the multiple frequency bands and multiple amplifiers for amplifying the transmitted signals on the same substrate, and arranges the multiple filters in close vicinity to the amplifier in the order where the multiple filters are excellent in their temperature characteristic.

An electrophotographic developing apparatus includes a photoreceptor drum supported for rotation in one direction, a rotatably supported developing roller disposed in face-to-face relation with the photoreceptor drum for supplying a single-component developing material, a rotatably supported charge transfer roller disposed on one side of the developing roll remote from the photoreceptor drum and in face-to-face relation with the developing roller for delivering the developing material onto the developing roller, a charged layer regulating member disposed around the charge transfer roller and cooperable with the charge transfer roller to regulate a charging and a layer of the developing material, and a developing hopper for accommodating the developing material to be supplied to the charge transfer member. In operation, the developing material within the hopper is carried by the charge transfer roller in the form of a charged toner layer which is subsequently delivered onto the developing roller. The toner layer on the developing layer is then deposited on an electrostatic latent image formed on the photoreceptor drum. At least one of a material for, a surface roughness of and a speed of movement of the developing roller differs from that of the charge transfer roller.

In order to avoid a load change which occurs when seam O passes by the heads affect image information, a dyeing layer transfer head and recording heads are located in equal intervals having length P, which is obtained by equally dividing an entire circumference K of a recording intermediate belt by n (n is integer), and, given that the position of the seam of the recording intermediate belt, which does not have an end obtained by coupling two ends of a belt body of a band shape, is origin O, images are formed in portions except for portions at origin O, or at a distance of 1×P, 2×P, . . . (n−1)×P from origin O. In this way, it is possible to prevent deterioration in the image quality, such as a stripe line in an image formed by an image forming apparatus.
