摘要:
A powder conveying device of the present invention includes a powder storing portion storing powder, and a pipe configured to guide the powder from the powder storing portion to a destination positioned below the powder storing portion. The pipe extends downward from the powder storing portion toward the destination, then bends with an inclination angle smaller than the preceding inclination angle relative to the horizontal, and then connects to the destination.

摘要:
An image forming apparatus performs electrophotographic image forming using a toner and includes an image bearing member configured to bear an electrostatic latent image on a surface thereof, a developing mechanism configured to develop the electrostatic latent image in to a toner image by using a toner, a transfer mechanism configured to transfer the toner image from the image bearing member to an image receiver, a cleaning mechanism including a cleaning blade and configured to remove a residual toner on the image bearing member after toner image is transferred to the image receiver. The toner includes a binder resin and a colorant, forms a toner powder layer, and satisfies an inequality Y≧−0.05X+0.029, in which “X” expresses a porosity of the toner powder layer after uniformly compressed at a constant force and “Y” expresses a torque value obtained by rotatably sticking a conical rotor into the toner powder layer.
摘要:
An image forming apparatus includes an image carrier, a charging unit that charges the image carrier, a latent image forming unit that forms a latent image on the image carrier, a developing unit that develops the latent image to form a toner image, a transferring unit that transfers the toner image to a recording medium, a cleaning unit that cleans toner remaining on the image carrier, a lubricant applying unit that applies a solid lubricant to a surface of the image carrier, and a detecting unit that detects whether the image carrier is brand new. The toner has an average roundness of 0.94 or more. The lubricant applying unit is operated when the detecting unit detects that the image carrier is brand new.
摘要:
An optical information medium providing a protective layer above an optically transparent substrate to protect a recording part, and can record information which is optically readable by means of laser beam. An aqueous printing ink-fixable, hydrophilic resin film is formed on the protective layer. Given letters and patterns can be printed easily and satisfactorily.
