摘要： An image formation apparatus having a cleaning process for removing defective toner from the developing unit during a non-image formation rotation of the photoreceptor drum. The image formation apparatus includes a reverse polarity charger for charging the photoreceptor drum to an opposite polarity from the polarity that is used for forming an electrostatic latent image. The reverse polarity charger allows defective toner to be removed from the surface of the photoreceptor during a warming-up process of the apparatus or after a predetermined number of image forming processes have been performed.

摘要： Electrophotographic apparatus according to this invention are controlled in different ways such that quality of produced images is not affected by deterioration of the developing agent or the condition of the photoreceptor. A timer may be provided to detect the duration of a rest period to adjust the speed of development accordingly as well as by the number of copies produced. Similar control may be effected by measuring the surface voltage of the photoreceptor by a voltage detector and by adjusting the output level of the principal charger used for uniformly charging the photoreceptor prior to a development process.

摘要： A photosensitive element is produced with a minimum amount of a conductive synthetic resin material. A draft for injection molding is formed in the inner circumferential surface as a supporting body, and a driven member provided with a gear is fixed to the end of the supporting body with a smaller inner diameter, that is, the thicker end. A driven portion in which a plurality of projections and depressions are formed alternately to be adjacent to each other in the circumferential direction is arranged on an axial end of a cylindrical supporting body made of a conductive synthetic resin, including a photosensitive layer on the outer circumferential surface. By a joint member removably engaged with the driven portion, the supporting body is rotated around the axis. In one arrangement, only the end of the supporting body is solid. In another arrangement, the supporting body is solid in the almost entire length in the axial direction.

摘要： The object of this invention is to provide an image forming apparatus capable of preventing decrease in image density at a rear end part of an image. A change in waveform in sensor outputs which is produced when a toner patch image is read by an optical sensor used for the process control is detected. The difference (Vg−Vd) between grid voltage Vg and development bias voltage Vd is changed only between a target value of 300 V corresponding to low-output side threshold value Va and a target value of 100 V corresponding to high-output side threshold value Vb according to the sensor output deflection &Dgr;V so that the difference (Vg−Vd) decreases as the image loss level increases. The difference between the grid voltage Vg and the development bias voltage Vd is set so as to prevent the image loss in the rear end part of an image.

摘要： Dimethylnaphthalenes are isomerized into 2,6-dimethylnaphthalene by utilizing hydrogen fluoride as a catalyst and straight chain saturated aliphatic hydrocarbons having carbon atoms in the range from 5 to 12 as the solvent. Isomerization to other undesirable isomers such as 2,7-dimethylnaphthalene and side reactions such as disproportionation are suppressed and a very high degree of the isomerization to 2,6-DMN can be attained.
