Abstract: A conveying device includes a housing, a linear driving mechanism, a first sliding assembly, a second sliding assembly, and a carrying mechanism. The linear driving mechanism is assembled within the housing. The first sliding assembly is slidably assembled together with the second sliding assembly within the housing, and both sliding assemblies are driven by the linear driving mechanism to slide horizontally. The carrying mechanism is slidably sandwiched between the first sliding assembly and the second sliding assembly. The first sliding assembly and the second sliding assembly are driven by the linear driving mechanism to slide within the housing along either a same direction or along opposite directions. The carrying mechanism may slide linearly together with the first sliding assembly and the second sliding assembly, or slide upwards and downwards perpendicular to the linear sliding direction of the first sliding assembly and the second sliding assembly.

Abstract: Organic photoreceptors of the functionally separated laminated type containing a hydrazone compound in the charge transport layer thereof which provides low crystallinity and improved sensitivity, durability, and reproducibility. The hydrazone compound disclosed in the present invention is presented by the following general formula (I): ##STR1## wherein R.sub.1 represents a substituted or unsubstituted C.sub.1 -C.sub.4 alkyl group, R.sub.2 represents a hydrogen atom, or an alkyl or alkoxy group; n is an integer of either 1 or 2; R.sub.3 and R.sub.4 each independently represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted aralkyl group; or alternatively R.sub.3 and R.sub.4 form a substituted or unsubstituted aromatic heterocyclic ring residue cojointly with the nitrogen atom to which they are bonded.
