摘要： A positional deviation correction pattern includes a first and second pattern image portions adjacent in a sub-scanning direction at the same position in a main-scanning direction, with the same width in the main-scanning direction. Each image portion includes a first side extending in the sub-scanning direction, a second side continuing from one end of the first side and extending in a direction intersecting the sub-scanning direction, and a third side continuing from the other end and extending in a direction intersecting both the sub-scanning direction and the second side. The second sides have the same inclination angle to a virtual line parallel to the main-scanning direction. The third sides have the same inclination angle to the virtual line. A length of one image portion in the sub-scanning direction gradually increases from one end to the other end in the main-scanning direction, a length of the other image portion gradually decreases.

摘要： A developing device for an image forming apparatus of the present invention includes an image carrier performing endless movement while carrying a developer in the form of a layer thereon, and a regulating member for regulating the thickness of the layer. Toner stored in the developing device is covered with an additive whose particle size is less than 2 &mgr;m. The regulating member is implemented as a doctor roller having a surface roughness Rz equal to or greater than the above particle size, but smaller than 2 &mgr;m. The doctor roller is pressed against a developing roller or developer carrier by a preselected pressure, forming a nip for development. The developing device reduces irregular development ascribable to impurities caught at a regulating position assigned to the doctor roller more than a conventional developing device using a doctor blade as a regulating member. In addition, the developing device obviates irregular development in the form of fine stripes ascribable to stripe-like irregularities formed in the developer layer existing on the developing roller.

摘要： A development apparatus includes a development roller, a supplying roller, and a toner layer regulating member. The development roller contacts an image carrying member and develops an electrostatic latent image into a toner image on the image carrying member. The development roller may be made of aluminum and is rotatably mounted in the apparatus. The supplying roller supplies toner to the development roller. The toner layer regulating member regulates the toner to form a thin film on the development roller. The toner layer regulating member has a roller shape, a surface roughness Rz in a range of from 0.5 &mgr;m to 2 &mgr;m, and a dynamic friction coefficient in a range of from 0.1 to 0.8.

摘要： An image forming apparatus including a photoconductive member, a charging member, a development mechanism, a transfer mechanism, and a power supply source. The development mechanism develops an image on the photoconductive member. The toner is normally charged with a voltage having a same polarity as the charge of the photoconductive member. The transfer mechanism includes a transfer roller to transfer the developed image from the photoconductive member onto a recording sheet. The power supply source supplies a voltage, having the same polarity as the voltage applied during a normal transfer operation, to the transfer roller when a region of the surface of the photoconductive member passes through a development region without a performance of a development operation and reaches a transfer region under a condition in which no recording sheet exists therebetween.
