摘要： An image forming apparatus includes a corona charger, first and second supporting members for supporting the corona charger on the respective sides of the corona charger with respect to the circumferential direction of a photosensitive member, and first and second urging portions for urging a shield of the corona charger in the first and second supporting members. The first urging portion and the second urging portion urge the shield at non-opposing positions relative to each other with respect to a longitudinal direction of the corona charger. The image forming apparatus enables suppression of charging non-uniformity due to vibration of the corona charger without impairing motion of a grid cleaning member.

摘要： An image forming apparatus includes a plurality of process cartridges provided for black and for another color. The process cartridges each including a set of a latent image carrier, a charging unit that charges a surface of the latent image carrier, and a lubricant applying unit that applies lubricant to the surface of the latent image carrier. The process cartridges for black and for the another color each has a cartridge frame with which the process cartridge is attachable to and removable from an apparatus body. The cartridge frames of the process cartridges for black and for the another color being of the same type. The process cartridge for black differs from the process cartridge for the another color in the configuration of the charging unit. The amounts of lubricant applied by the lubricant applying units to the respective latent image carriers differ with respect to the configuration of the charging unit.

摘要： A pulse-like DC voltage is applied from two power sources to transfer residual toner uniformizing means and toner charge amount control means, respectively, to expel transfer residual toner deposited on these means from these means onto a photosensitive drum. In a low humidity environment, the number of application of the DC voltage is increased so as to sufficiently expel the transfer residual toner because the transfer residual toner is less liable to be expelled even when the pulse-like DC voltage is applied to the above two means in the low humidity environment in which an absolute moisture content in atmosphere is small and electrical resistances at portions of a photosensitive drum contacting the above two means.

摘要： A guide is used to protect a corona cartridge during shipping and during insertion into an electrostatic marking apparatus. The guide has dimensions that will permit the cartridge to fit therein and has a locking mechanism that securely holds the cartridge in place during shipment or movement. When the cartridge is to be removed from the guide and inserted into an electrostatic marking system, a handle attached to a latch is used to free the latch from a groove in the guide. The groove in the guide is located between two upwardly protruding ramps having a slidable side and a locking side that abuts the latch and holds it in place until activation when the latch handle frees it from the groove.

摘要： An image forming apparatus with an image bearing member and a charging member for contactably charging the image bearing member. The charging member is provided within an exchangeable unit. An electric power containing an AC component is applied to the charging member, and adjustments are made to the magnitude of the AC component. When the exchangeable unit is exchanged, the magnitude of the AC component is returned to an initial value thereof, so as to extend the life of the image bearing member in situations where the exchangeable unit is exchanged and the AC component might otherwise have a magnitude inappropriate for the new unit.

摘要： A cartridge is provided in which an electrifying roller is driven in a counter direction to photosensitive member drum and which has a toner remaining amount detection means and a memory, and the electrifying roller is driven by an electrifying roller drive motor. The electrifying roller optimum rotation speed stored in the memory in advance is accessed when the toner remaining amount reaches a predetermined value, and the electrifying roller rotation speed is changed in accordance with the electrifying roller optimum rotation speed. The accumulated distance by which the photosensitive member drum and the electrifying roller abrasively slide is written in the memory, and when the toner remaining amount reaches a predetermined value, the electrifying roller optimum rotation speed corresponding to the abrasively sliding distance is accessed. The electrifying roller rotation speed is changed in accordance with the electrifying roller optimum rotation speed.
