A fixing apparatus includes a heating roller and a nip forming unit facing the heating roller to form a fixing nip. The heating roller includes a resistive heating layer receiving an electric current to generate heat, and a base material supporting the resistive heating layer, wherein a resistance per unit length of the resistive heating layer at opposite sides in a length direction is less than a resistance per unit length of the resistive heating layer at a center portion.

Fixing apparatus and electrophotographic image forming apparatus including the same

A magnetic recording and/or reproducing apparatus includes a single main slide member for interlocking the respective portions of a deck, a master gear member for moving the main slide member and a motor for driving the master gear member. The master gear member is engaged with a rack formed on the main slide member. The deck and a loading device for loading a cassette onto the deck are sequentially driven by the motor. The rack allows for mechanically stable operation and rapid mode change.

Magnetic recording and reproducing apparatus having a single master gear

An apparatus for preventing accidental recording of a tape recorder is disclosed. The apparatus detects the presence or absence of the protecting piece of a tape cassette and outputs control signals for discriminating the allowance or prohibition of the recording. The apparatus utilizes a light sensing device without any switching contacts thereby assuring the reliability of the operation.
