摘要： The present invention provides a charging device which comprises a charging roller (14a) and a cleaning component (14b). The charging roller charges a surface of an image-recording medium (11) with a voltage which is applied from an external source. The cleaning component cleans a surface of the charging roller. The charging roller includes a resistance adjustment layer which is made of a resin composite and formed on an outer periphery of a core metal. The hardness of the charging roller is 45 degrees or more in JIS D hardness. The cleaning component has a portion which is in contact with the charging roller. This portion is made of resin foam which has a continuous foam structure. The density of the resin foam is 5 to 15 kg/m 3 and its tensile strength is 1.7±0.5 kg/cm 2 .
摘要翻译：本发明提供一种充电装置，其包括充电辊（14a）和清洁部件（14b）。充电辊以从外部源施加的电压对图像记录介质（11）的表面充电。清洁部件清洁充电辊的表面。充电辊包括由树脂复合材料制成并形成在芯金属的外周上的电阻调节层。充电辊的硬度在JIS D硬度上为45度以上。清洁部件具有与充电辊接触的部分。该部分由具有连续泡沫结构的树脂泡沫制成。树脂发泡体的密度为5〜15kg / m 3，拉伸强度为1.7±0.5kg / cm 2。

摘要： An image forming apparatus (1) in which multiple different type developers are usable includes an image forming unit (206); a cleaning device (213; 218); a collected developer passage (220); a rotatable developer conveyor (92) to transport developer collected by the cleaning device (213; 218) in the collected developer passage (220); a temporary developer container (225); a waste-developer container (226); and a controller (100) to control conveyance of the collected developer from the cleaning device (213; 218). The controller (100) refers to a developer type database in which each of the multiple different type developers is correlated with a conveyance condition to transport the collected developer. One of the multiple different type developers is set as the target developer, and the controller (100) changes the conveyance condition according to the developer type database when a content of an image output job indicates that a target developer is used.
摘要翻译：其中可使用多种不同类型的显影剂的图像形成设备（1）包括图像形成单元（206）清洁装置（213; 218）; 收集的显影剂通道（220）; 可旋转的显影剂传送器（92），用于传送由收集的显影剂通道（220）中的清洁装置（213; 218）收集的显影剂; 临时显影剂容器（225）; 废显影剂容器（226）; 和控制器（100），用于控制从清洁装置（213; 218）收集的显影剂的输送。控制器（100）是指开发者类型数据库，其中多个不同类型的开发者中的每一个与输送条件相关联以输送收集的显影剂。将多个不同类型的开发者中的一个设置为目标开发者，并且当图像输出作业的内容指示使用目标开发者时，控制器（100）根据开发者类型数据库改变传送条件。
